Advanced Artificial Dielectric Materials for Millimeter Wavelength Applications.

Abstract

An artificial dielectric polymeric composite containing alloy particles which are oxide-coated for isolation and ferromagnetic below room temperature for packing determination, is described. Induced magnetic dipole effects are calculated and compared with measurements of complex permeability in the centimeter wavelength range. Dielectric behavior, according to various theoretical model of hetergeneous media, is explored and correlated to experimental systems. Evidence of higher-order multipole effects and packing-limit effects in random composites is presented. Several advanced preparation techniques for fine powder were initiated. (Author)
