Abstract
A BROADBAND (5-20 GHZ) HIGH PERFORMANCE THIN ABSORBER THAT UTILIZES FERRITES AND IS BASED ON THE FERROMAGNETIC RESONANCE (FMR) PHENOMENA IS PROPOSED. CRYSTALLINE STRUCTURES THAT HAVE A HIGH RESIDUAL MAGNETIZATION (ANISOTROPIC FIELD) AND WHICH WILL BE USED A MIXTURE OF FERRITE MATERIALS WITH DIFFERENT FMR'S (ACHIEVED BY DOPING) ARE SUSPENDED IN A FLEXIBLE MATRIX. THE EFFECTS OF ALIGNMENT DURING CURE ARE CONSIDERED, IN ADDITION TO THE INTRODUCTION OF NONALIGNED CRYSTALS INTO THE COMPOSITE. THE FOCI OF THE PHASE I RESEARCH ARE MANUFACTURING METHODOLOGY, ALTERNATE APPROACHES TO ACHIEVE BROADBANDING, AND PERFORMANCE TRADES FOR DIFFERENT CONFIGURATIONS. CALCULATIONS WILL BE PERFORMED ON MWT'S VAX 11/730 COMPUTER. DURING THE PHASE I STUDY, A FEASIBILITY DEMONSTRATION WILL BE CONDUCTED UTILIZING CURRENTLY AVAILABLE FERRITE MATERIALS.
