Electromagetic Pulse Diffraction by a Moving Half-Plane

Abstract

Abstract-This paper is concerned with the scattering of an electromagnetic (EM) pulse by a perfectly conducting half-plane, moving in a free space. It is assumed that the source signal is a plane wave pulse with its envelope described by a Dirac delta function. The representation for the total field is found, and physical interpretation of the solution is given. This representation, valid for all screen velocities, is then reduced to the case of moderate and low velocities, important for practical applications.

Diffraction of a Plane Inhomogeneous Electromagnetic Wave by a Perfectly Conducting Half-Plane in an Absorbing Medium

“…Returning to Equations (8), note that from (8a) we yield at once: A(β)=A − (β), i.e. the function A(β) is analytic in the lower complex half-plane and has not poles there.…”

“…From that time, this solution has been generalized more than once to the cases of impedance boundary conditions on a half-plane [6], a perfectly transparent half-plane [7], a moving half-plane [8], on the case of half-plane embedded into bi-isotropic medium [9], and also on the case of different media disposed bilaterally along that [10]. The solution for a plane incident wave has stood duty as the bases for the solutions obtained for a vector spherical wave [11] and for electromagnetic beams [6,12].…”

Diffraction of Em Plane Wave by a Slit in an Impedance Plane Using Maliuzhinets Function

“…Moreover, the application of geometrical theory of diffraction (GTD) to the scattering from a wedge with impedance faces is applicable to the analysis of practical structures involving edges in an impedance surface. It may be noted that scattering from slits, half plane, impedance surfaces and study of high frequency diffraction are topics of current interest [2][3][4][5][6][7][8][9][10][11][12][13].…”

A Note on Spherical Electromagnetic Wave Diffraction by a Perfectly Conducting Strip in a Homogeneous Bi-Isotropic Medium

“…In recent years, propagation of plane waves with negative phase velocity and its related applications in isotropic chiral materials can be found in [23][24][25][26]. It may be noted that scattering from strips, slits, half plane, impedance surfaces and study of high frequency diffraction are topics of current interest [37][38][39][40][41][42][43][44][45][46][47][48].…”
