Diffraction 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 کاملVector diffraction theory for electromagnetic waves.
The scalar Huygens-Fresnel principle is reformulated to take into account the vector nature of light and its associated directed electric and magnetic fields. Based on Maxwell's equations, a vector Huygens secondary source is developed in terms of the fundamental radiating units of electromagnetism: the electric and magnetic dipoles. The formulation is in terms of the vector potential from whic...

متن کاملNumerical Solution of Cylindrically Converging Shock Waves
Abstract—The cylindrically converging shock wave was numerically simulated by solving the Euler equations in cylindrical coordinates with TVD scheme and MUSCL [1] approach, using Roe's approximate Riemann solver [2] and super-bee nonlinear limiter [3]. The present study used the in house code developed for this purpose. The behavior of the solution in the vicinity of axis is investigated and ...
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...
