Electromagnetic scattering by buried objects of low contrast

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...

Low-Frequency Electromagnetic Scattering

The main result of this paper is to reduce the calculation of higher-order terms in the asymptotic expansions of the electric and magnetic elds at low frequencies to the solutions of certain canonical problems. We also provide a new and simple variational proof of the convergence of the electric and magnetic elds solutions of the scattering problem for the Maxwell equations as the frequency goe...

Electromagnetic Scattering from a Perfect Electromagnetic Conductor Cylinder Buried in a Dielectric Half-space

An analytical solution is presented for the electromagnetic scattering from a perfect electromagnetic conducting circular cylinder, embedded in the dielectric half-space. The solution utilizes the spectral (plane wave) representations of the fields and accounts for all the multiple interactions between the buried circular cylinder and the dielectric interface separating the two half spaces.

Free-space Relativistic Low-frequency Scattering by Moving Objects

The present study brings together two aspects of electromagnetic theory: the recently discussed low-frequency series expansions based on the concept of Consistent Maxwell Systems, and Einstein’s Relativistic Electrodynamics. Combined, this facilitates the analysis of pertinent low-frequency scattering problems involving objects moving with arbitrary constant velocities in free space. The low-fr...
