Electromagnetic Wave Scattering by Small Impedance Particles

Scattering of electromagnetic (EM) waves by one and many small (ka 1) impedance particles Dm of an arbitrary shape, embedded in a homogeneous medium, is studied. Analytic formula for the field, scattered by one particle, is derived. The scattered field is of the order O(a2−κ), where κ ∈ [0, 1) is a number. This field is much larger than in the Rayleigh-type scattering. An equation is derived fo...

Electromagnetic wave scattering by many small particles

Scattering of electromagnetic waves by many small particles of arbitrary shapes is reduced rigorously to solving linear algebraic system of equations bypassing the usual usage of integral equations. The matrix elements of this linear algebraic system have physical meaning. They are expressed in terms of the electric and magnetic polarizability tensors. Analytical formulas are given for calculat...

Electromagnetic Wave Scattering by Randomly Buried Particles

In this thesis, the effect of volume scattering from the buried particles in half-space random media on the radar backscattering cross section is investigated. The radar clutter from a flat desert area is modeled as spherical scatterers randomly embedded within a layered medium with flat interfaces. Three approaches are used to calculate the backscattering coefficients. The Monte Carlo method b...
