University of Missouri--Kansas City, 2021Geometric transformers are often used in radar and communications systems to transition between signal driving and radiating elements that terminate in significantly different geometries with unity input/output impedance. This work demonstrates the design and construction process of a geometric transformer with comparison to simulation and prior art. The focus of this work is on the design, optimization, build and test results of a novel geometric transformer capable of transmitting kilovolt 100-picosecond pulses from a parallel plate geometry into a coaxial geometry, modeled after a transverse electromagnetic (TEM) cell. The transformer operates on a wide frequency bandwidth (.5-2 GHz) with minimal reflection or radiative loss (>1.5 dB loss across the frequency range for both in testing). Further, this work touches on a future project that faces similar challenges under different requirements, and describes how these projects compare in design, production, and outcome.Introduction -- Methods -- Transformer -- Further methods -- Conclusio
