Advanced Artificial Dielectric Materials for Millimeter Wavelength Applications. Part A
Abstract
This is Part A of a two-part Annual Report. (Part B is classified.) This part describes a continuation and completion of work on non-magnetic composite artificial dielectrics. The electromagnetic evaluation of polymer- based composites was improved in the region of 2-18 GHz and extended to include Ka (26-40 GHz) and W (75-110 GHz) bands, through cooperation at NRL. Permittivity variations with frequency were essentially negligible. Induced permeability results were significant and were consistent with calculated models and data of earlier parts of this program. Previous results for permittivity versus volume loading were reinforced. The effect of binder permittivity was studied using an alternative inorganic binder. Qualitatively similar results were found, which scaled reasonably well to the binder permittivity as predicted. The permittivity behavior versus volume loading for randomly packed artificial dielectrics was modeled empirically from several ideal experiments and theoretically from a simplified model yields a satisfactory predictive control in considering the properties of such artificial dielectric materials.
