Rigorous Expressions for the Equivalent Edge Currents
An exact form for the equivalent edge current is derived by using the axioms of the modified theory of physical optics and the canonical problem of half-plane. The edge current is expressed in terms of the parameters of incident and scattered rays. The analogy of the method with the boundary diffraction wave theory is put forward. The edge and corner diffracted waves are derived for the problem...
متن کاملHigher Order Equivalent Edge Currents for Fringe Wave Radar Scattering by Perfectly Conducting Polygonal Plates
-Two sets of higher order equivalent edge currents are introduced which, in combination, account for the first-, the second-, and part of the third-order edge diffraction caused by the fringe wave surface current induced on a perfectly conducting polygonal plate in a radar scattering configuration. The first set represents the fringe wave surface current excited by the incident plane wave at th...
متن کاملTransient Coherent Raman Scattering in the Time and Frequency Domain
A new type of Raman spectroscopy is presented: After transient excitation of molecular modes coherently scattered Raman spectra are investigated in" a delayed probing experiment. The spectral position of the Raman mode is observed after long delay times. The dephasing time is obtained from the time dependence of the scattered amplitudes. Frequency disturbing non-resonant susceptibilities are el...
متن کاملEquivalent isotropic scattering formulation for transient short-pulse radiative transfer in anisotropic scattering planar media.
An isotropic scaling formulation is evaluated for transient radiative transfer in a one-dimensional planar slab subject to collimated and/or diffuse irradiation. The Monte Carlo method is used to implement the equivalent scattering and exact simulations of the transient short-pulse radiation transport through forward and backward anisotropic scattering planar media. The scaled equivalent isotro...
متن کاملTime-domain Cfie for the Analysis of Transient Scattering from Arbitrarily Shaped 3d Conducting Objects
A time-domain combined field integral equation (CFIE) is presented to obtain the transient scattering response from arbitrarily shaped three-dimensional (3D) conducting bodies. This formulation is based on a linear combination of the time-domain electric field integral equation (EFIE) with the magnetic field integral equation (MFIE). The time derivative of the magnetic vector potential in EFIE ...
