The analysis and simulation of the solid materials is done by employing a hollow cylindrical cavity resonator. This method provides parameters of high accuracy for calculating the permittivity and permeability of solid materials. The dielectric properties of hollow cavity are first determined by measuring resonant frequency and quality factor. Then, the same analysis has been carried out by …show more content…
New artificial materials called meta-materials have some interesting electromagnetic characteristics that is not found in nature. One of the characteristics is the negative index of refraction which is realized by combining negative permittivity and permeability. These negative permittivity and permeability are commonly realized by split ring resonators (SRRs). Here, a mathematical formulation is adopted for analytical derivation of dielectric constants of non-magnetic solid materials. For this, the geometry of cylindrical single split ring resonator is defined with the parameters like inner radius (R), thickness (w), height (h), and gap width (g). The sub-wavelength split ring resonator is characterized by inductance (L) and capacitance (C). The geometry of split ring resonator with designing parameters is shown in the Fig.
The output frequency of divider gets divided by 4 ie 1.05 GHz. Since for practical realization, one cannot directly give RF signal directly to frequency divider input pin to avoid huge impedance mismatch. Use of microstrip line[4] in the ter- mination allows for smooth transition of signal from SMA probe to Microstrip and further 27 Figure 4.10: Divided output of divide-by-4 ip op to frequency divider pin. The schematic of divide-by-4 with microstrip is shown below in Figure 4.11.
For this lab the objective is to see how the properties of individual substances compare with properties of mixed substances. For this lab the research questions is mixture, homogenous mixture, and heterogeneous mixture. A mixture is a combination of 2 or more substances that are mixed together physically but not combined chemically. Also a homogeneous mixture is a uniform in structure or composition throughout the substance. Lastly, a heterogeneous mixture is a consisting of dissimilar parts of elements (not the same).
The mobile phase used was a mixture of ammonium acetate buffer and acetonitrile at a ratio of 400:600. A flow rate of 1 mL/min was maintained, and the detection wavelength was 292 nm (22). The required studies were carried out to estimate the precision and accuracy of the HPLC method and were found to be within limits [percent coefficient of variation was less than 15%]. Sample preparation briefly involved 0.4 μ membrane filter through which the sample was filtered, diluted with mobile phase, and 10 μL was spiked into
In this lab experiment, I experimented with 2 different amount of borax (1g and 5g) to see if the amount of borax affects the bounce height of the ball. The ball is made up of polyvinyl acetate (school glue), borax and water. In the experiment the independent variable is borax and the dependent variable is the bounce height. I found out that borax has sort of a protective layer that creates the bounciness. Therefore, I hypothesized that the more borax that is used, it would be more bouncy, because there is more of a protective layer to it.
Use the evidence provided by the tests to identify the mystery powder. The mystery powder (#5) is the baking powder. My partners and I figured this out because the physical and chemical properties of both of the substances are very similar. For example, both powders are not soluble in water, and they both turned red when they reacted with the universal indicator.

Background: In order for barium sulfate to be a product, we decided to perform a double replacement reaction.
Ct ε0A (9)where ε0is the permittivity of the free space, C is the capacitance, t isthe thickness of the sample and A is the area of the cross section. Thedielectric constant has high values in the lower frequency regionand then it decreases with the applied log frequency as shown inFig. 10(a). The plot of the dielectric loss vs.
So these would tend to have more reflections building up, to see that the biggest buildup is in the 400Hz band gives an idea how these materials can influence each other to resonate at a lower range than the previous
Jaspreet Singh Professor Paratore Biology 1 November 1, 2014 Spectrophotometry Identifying Solutes and Determining Their Concentration Statement of the Exercise or of the Problem The purpose of the lab experiment was to attain the following objectives: • Learning to Operate the Spectrophotometer • Construct absorption spectra for cobalt chloride and chlorophyll. Hypothesis If greater and higher concentrations of cobalt chloride are added to each solution then greater amounts of light would be absorbed by each solution. Thus a liner relationship will result in which the absorbance of a substance would be proportional to its concentration, which will be depicted, in a linear graph.
Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

It was found that the unknown compound smell like chorine, was soluble in water. The flame test matches the color of calcium chorine indicating that the unknown compound contained chorine, also the anion test sodium chorine proved to be positive.
It was the opposite, with the lowest frequency tuning forks that caused resonance at a higher length. There were many observations, calculations (wavelength, the speed of sound, and percent area from actual speed of sound), a graph comparing the length of two different tubes, and analysis questions. The results of the data showed that the tuning forks with the highest frequency had the shortest tube length. For example, for the 512 Hz of the open-open tube, the distance was .335m and the open-closed tube had .300m. This resulted in the wavelength to be the lowest also. Therefore, the lowest frequencies had the largest tube distance and wavelength.
Properties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
Experiment #7: Column Chromatography of Food Dye Arianne Jan D. Tuozo Mr. Carlos Edward B. Santos October 12, 2015 Abstract Column chromatography is the separation of mixture’s components through a column. Before proceeding with the column chromatography itself, a proper solvent system must be chosen among the different solvents. The green colored food dye is the mixture whose components are separated.
The experiment was conducted by allowing monochromatic light from a sodium lamp, which is a monochromatic source, to fall normally onto the plano-convex lens. The light underwent reflection and refraction and was observed by a travelling microscope. It was shown that the theory of Newton’s rings has practical
