SEEKER TRANSCEIVERS

MILLIMETER-WAVE SYSTEMS ARE RAPIDLY EMERGING WITH NUMEROUS APPLICATIONS, INCLUDING GUIDANCE FOR SELF-CONTAINED MUNITION. VIABILITY OF MANY MILLIMETER-WAVE SYSTEMS RELIES HEAVILY UPON ACHIEVING THE LOWER COST AND SMALL SIZE AFFORDED BY CIRCUIT INTEGRATION TECHNIQUES. DIEELECTRIC-BASED WAVEGUIDES, SUCH AS INSULAR LINE, ARE HIGHLY APPROPRIATED MEDIA FOR SYSTEM INTEGRATION BY FABRICATING ALL CIRCUIT COMPONENTS BY SUITABLY MODIFYING THE BASIC WAVEGUIDE. CIRCULATORS ARE AN ESSENTIAL COMPONENT OF PRACTICALLY ALL THE SYSTEMS. HOWEVER, INTEGRABLE VERSIONS OF DIELECTRIC BASED WIDEBAND CIRCULATORS HAVE NOT BEEN FULLY DEVELOPED AS YET. THE PROPOSED RESEARCH WILL STUDY AND DEVELOP HIGH PERFORMANCE INSULAR GUIDE CIRCULATORS. DESIGN CONCEPTS FOR FUNDAMENTAL AND HIGHER ORDER MODE FERRITE POST CIRCULATORS ARE PROPOSED. THEORETICAL WORK WILL FOCUS ON THE MODEL CHARACTERIZATION OF THE FERRITE POST AND ANALYTIC PERFORMANCE COMPUTATIONS. PROTOTYPE WILL BE FABRICATED AND TESTED TO VERIGY THEORY AND TO ESTABLISH OPTIMIZATION PROCEDURES USING THE MOST RECENTLY AVAILABLE, HIGH QUALITY FERRITE AND ALUMINA DIELECTRIC MATERIALS.
