Essay On Surface Polariton

1251 Words6 Pages

Surface Plasmon Polariton is the electromagnetic wave that passes to the surface of metal and air. The Plasmon indicates the wave’s passes to the metal and the Polariton indicate the wave passes in the air. The development of surface Plasmon Polariton is achieved by the excitation of photon and electron. When the electron passes on the metal surface then strike on it and disperses into air as a Polariton. The scattered waves are parallel to the surface of metal. Other method of surface Plasmon Polariton is striking by photon but, for that purpose both have the same frequency and momentum so use prism for excitation of photon. The dispersion relation of the waves represent the level of spreading on the metal which mostly depend upon the nature of waves striking, its frequency and wave number. Dispersion speed are different in different wavelength of waves, so speed of wave is function of its wavelength. The dispersion relation of a wave determined by the angular frequency and its wavenumber like as, w(k)=v(k).k in which w(k) is angular frequency and k is wave number. …show more content…

To identify the characterization of surface Plasmon Polariton by the two media in which one of the act as convex and other act as a concave, when waves passes on the dielectric phase then as a convex while on the surface as concave, (Liaw and Wu, 2008). Recent century of the world going to research on the plasmonic circuit due to having extensive properties like optic and electronic circuit, because these circuit have surface Plasmon Polariton which is two dimensional spreading of waves one in to metal surface and other in the air, (Holmgaard and Bozhevolnyi,

  • The Cold Equations By Tom Godwin Analysis

    653 Words  | 3 Pages

    The story Cold Equations by Tom Godwin, and the poem Traveling Through the Dark by William Stafford, both use two components of moral reasoning; moral judgment, and moral motivation. Cold Equations takes place in outer space where a slight increase in mass not included in the original calculations could get someone killed. Traveling Through the Dark takes place in 1962 on a road probably countryside. An example of moral reasoning is moral judgement, or the ability to correctly reason in regards of certain circumstances. In The Cold Equations Barton the Pilot of the EDS ship finds a stowaway who boarded the ship illegally and says “These ships are given barely enough fuel to reach their destination, and if you stay aboard, your added weight will cause it to use up all its fuel before it reaches the ground.

    The Submarine is a vessel that can function both above water as well as underwater (Submarine). The first submarine was built by the dutch inventor Cornelius van Drebel, and its design was first refined during the American Revolutionary War (Submarine). The submarine was used in many wars, but did not show great success until World War I and World War II (Submarine). It was during these wars that germany began calling their fleet of submarines U-Boats. The U-Boat during world war I was the same as most experimental submarines except for the fact that it included torpedoes for weapons and was built stealthier than the earlier submarines (U-boat).

    In other words, Compton scattering occurs when only part of the photon energy is transferred to a free electron and the photon scatters with lower energy than the incident one. This increases the wavelength of the photon and increase the kinetic energy of the electron. The increase in wavelength is found to be . This can only happen if light behaves like particle. In fact, light has both wave-like and particle-like behavior.

  • Political Polarization Essay

    In his Farewell Address, George Washington warned Americans about the effects of political polarization, saying,“One of the expedients of party to acquire influence, within particular districts, is to misrepresent the opinions and aims of other districts.” Polarization is the division into two sharply contrasting groups or sets of opinions or beliefs. The political gap between Democrats and Republicans has been a growing problem but has seemed to get increasingly worse in recent years. Although the two-party system can help create balance within the government, political polarization is detrimental to American society because it causes tension between citizens and effects our daily lives. Ideological differences are visibly the main

    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.

Group Dynamics: - Lewin’s definition of a group is widely accepted. Here the basic line of argument is that groups come into being in a psychological sense ‘not because their members necessarily are similar to one another (although they may be); rather, a group exists when people in it realize their fate depends on the fate of the group as a whole’
