Abstract
HIGHLY ANISOTROPIC ALIGNED UNIAXIAL POLYCRSTALLIVE HEXAGONAL FERRITE COMPOUNDS POSSES BUILT-IN EFFECTIVE MAGNETIC FIELDS. THESE MATERIALS POSSESS ATTRACTIVE MICROWAVE AND MAGNETIC PROPERTIES OF POTENTIAL IMPORTANCE TO ACHIEVE IMPROVED PERFORMANCE IN AND INNOVATIVE STRUCTURES FOR NONRECIPROCAL CIRCUIT FUNCTIONS AT NEAR-MILLIMETER WAVE FREQUENCIES. INVESTIGATIONS WILL BE CONDUCTED FOR THE EVALUATION OF THESES MATERIALS IN A RESONANCE ISOLATOR WAVEGUIDE STRUCTURE, A WAVEGUIDE Y-JUNCTION XIRXULATOR, AND A PHASE SHIFT TYPE FOUR-PORT WAVEGUIDE DUPLEXER. THE FREQUENCY OF EVALUATION WILL BE AT 94 GHZ PERFORMANCE ACHIEVED WILL BE COMPARED TO THAT PROVIDED FROM CONVENTIONAL SPINEL FERRITES. THE RESULTS OF THESE PERFORMANCE EVALUATIONS STUDIES WILL BE USED TO ASSESS AND PREDICT PERFORMANCE AT HIGHER FREQUENCIES, TO PROVIDE INFORMATION ON THE LEVEL AND MAGNITUDE OF THE RF-FERRITE INTERACTION PARAMETERS WHICH CAN BE USED TO CONCEIVE AND PREDICT PERFORMANCE IN MORE INVOVATIVE STRUCTURES AND TO ASSIST IN IDENTIFY- ING AND ADDRESSING CFRITICAL MATERIAL PROBLEMS,LIMITATIONS AND OPPORTUNITIES.
