Abstract:

Theoretical and experimental research was conducted to determine the electromagnetic scattering from heterogeneous dielectric bodies. The discrepancies in the literature regarding the singularity of the electric dyadic Greens functions were resolved. Compact range scattering measurements at 1 GHz were successfully performed. Extensive computations were made for a variety of dielectric scatterers, including a one-foot bird at 1 GHz. The agreements between measurements and computation were good except for the resonant sphere, for which the calculated resonant frequencies were shifted by about 20 percent. Various numerical techniques, to treat symmetrical scatterers, using symmetric matrices, banded matrices, and virtual memory were implemented in the Volume Integral Equation algorithm. Author
