The Physical Optic (PO) surface integral has been expressed in its basic components by the unique Modified Edge Representation (MER) currents line integration definition. The Scatterer Geometrical Optics (SGO) component field is associated with the Stationary Phase Point (SPP) bellowing to the illuminated region of the scatterer and the diffracted field component with its illuminated boundary. ...

An efficient wide-band analysis that combines modified integral equation-physical optics (IE-PO) hybrid formulation with the best uniform approximation is proposed for antennas around an electrically large platform in this paper. The modified single-level Fast Fourier Transform (FFT) algorithm which is based on the subdomain FFT acceleration is employed by interpolating the Green’s function and...

Geometrical optics (GO), the most widely used tool in analysis of high frequency electromagnetic problems, provides the first term of an asymptotic series solution to the Maxwell's equations [1]. It is implemented completely by employing the ordinary ray-tracing technique. To include the second asymptotic term systematically, Keller [2] suggested a generalization of the Fermat's principle on di...

We have investigated two kinds of hybrid methods for the electromagnetic scattering problem in the mid-frequency range. These are, a current-based approximation to the Magnetic Field Integral Equation called Physical Optics (PO) and the ray-based method Geometrical Theory of Diiraction (GTD), both combined with the Method of Moments (MM) such that MM is used on details that are small compared t...

In this study physical optics (PO) surface current is obtained by using the Malyughinetz solution to get scattered field expression for a truncated cylindrical conductive cap satisfying related boundary conditions given throughout paper. This done inverse edge point method transformation from wave diffraction half plane cylinder. can be used examine and scattering phenomena curved surfaces havi...

Unlike a generally rough ground surface, the sea surface varies over time. To analyze impact of motion waves on synthetic aperture radar (SAR) image target, wideband echo simulation method based frequency domain is used. For echo, electromagnetic (EM) scattering properties main components are analyzed by method. Based EM properties, can be accurately simulated using inverse fast Fourier transfo...

The suitability of various radiating systems for generating a directive high power microwave (HPhl ) beam is investigated. It is concluded that offset reflector antenna systems are well suited for this purpose. An HPM reflector antenna may consist of one or two reflectors that are illuminated by single or array feeds. To accurately predict the performance of an HPM reflector antenna, a versatil...

Diffraction of an electromagnetic plane wave from a slit in an impedance plane placed at the interface of two different media, has been formulated rigorously. Both the principal polarizations are considered. The method of analysis is Kobayashi Potential (KP). To determine the unknown weighting functions, boundary conditions are imposed which resulted into dual integral equations (DIEs). These D...
