An Analytic Solution of Transient Scattering From Perfectly Conducting Ellipsoidal Surfaces Illuminated by an Electromagnetic Plane Wave

This paper presents an analytical and closed-form solution, using a time domain (TD) physical optics (PO), for the fast analysis of transient scattering from a finite and perfectly conducting ellipsoidal surface when it is illuminated by a transient-step plane wave. The advantage of ellipsoidal shap...

Description
Summary:This paper presents an analytical and closed-form solution, using a time domain (TD) physical optics (PO), for the fast analysis of transient scattering from a finite and perfectly conducting ellipsoidal surface when it is illuminated by a transient-step plane wave. The advantage of ellipsoidal shapes to resemble a variety of realistic surfaces such as spherical, parabolic or planar surfaces allows the developed solution applicable to model a realistic scattering object such as an aircraft in an effective fashion. Physical appealing interpretation of wave phenomena in terms of reflection and diffraction mechanisms is also provided in the solution. Numerical examples are presented to demonstrate its physical phenomena of scattering mechanisms.
