Frequency selective surfaces for extreme applications

Jay Houston Barton, University of Texas at El Paso


It is known that for high-power microwaves and other extreme environments, the use of resonant metallic elements in frequency selective surfaces can be problematic. The solution developed within this dissertation to solve these problems was to use guided-mode resonance phenomenon to create all-dielectric frequency selective surfaces that could survive these extreme environments. To fully understand how these devices work, three different computational electromagnetic methods are formulated and implemented. The formulation of these methods start with the differential form of Maxwell’s equation and are derived all the way down to the final simulation state. This is done sequentially and all the work is shown for comprehension and completeness. These computational electromagnetic methods are then implemented into two different heuristic optimization algorithms. These optimization algorithms are used to develop three new and novel devices that solve the problems associated with all-dielectric frequency selective surfaces. All the devices developed in this work have been manufactured and experimentally tested. In the case of the high power devices, these were tested at the High Power Microwave Test Facility at White Sands Missile Range. One of the devices developed has the distinction of being the first known 3D printed all-dielectric frequency selective surface. The devices developed in this work have survived environments where any known metallic frequency selective surfaces are destroyed and rendered useless. This work provides novel new frequency selective surfaces for these extreme applications.
