Design and Simulation of a Metal-Insulator-Metal Filter Based on Plasmonic Split Ring
In this paper, a plasmonic filter made of a split ring, two U-shaped structures and two straight waveguides is designed and investigated. In the proposed structure, the split ring and U-shaped structures are situated between straight waveguides. Simulations are done based on FDTD method. Split ring, U-shaped structures and straight waveguides are made of air in the silver background. In the pro...
متن کاملDiffraction of Electromagnetic Waves
The general method to obtain solutions of the Maxwellian equations from scalar representatives is developed and applied to the diffraction of electromagnetic waves. Kirchhoff’s integral is modified to provide explicit expressions for these representatives. The respective integrals are then evaluated using the method of stationary phase in two dimensions. Hitherto unknown formulae for the polari...
متن کاملnumerical analysis of combined refraction and diffraction of waves
refraction and diffraction combination of waves, is very important and applicable problem in coastal engineering (e.g. for designing break - water). however, formulation of this phenomen and numerical solution is very difficult. in this study, a numerical algorithm based on the mild slop sea bed theory is presented to obtain the appropriate governing equations of combined refraction diffraction...
متن کاملKapitza-Dirac diffraction without standing waves: diffraction without a grating?
We discuss electron diffraction from two counterpropagating light waves with two different frequencies. We show that, even though these waves do not form a standing wave, electron diffraction similar to the conventional Kapitza-Dirac effect, i.e., scattering on a standing wave, is still possible. The nonlinear response of the electron to the laser fields creates a stationary diffraction grating...
متن کاملCosmic sound waves rule
© 2008 American Institute of Physics, S-0031-9228-0804-010-6 Relativistic sound waves raced through the hot plasma that filled the universe for its first 380 000 years. That sound left an imprint that is still discernible in the cosmic microwave background and also in the large-scale distribution of galaxies. Measurements of the sound waves manifested in the CMB, coupled with a detailed underst...
