Synthesis of microwave structures by inversion of the TLM process.

Abstract

This thesis presents a novel numerical synthesis technique based on the time reversal property of the Transmission-Line Matrix method (TLM). It allows the designer to generate the geometry of a passive circuit from its desired frequency response using alternate forward and backward time-domain analyses. This approach opens new doors in microwave synthesis and offers an advantageous alternative to the traditional synthesis techniques using frequency domain analysis. To demonstrate and validate the procedure, an inductive obstacle inside a waveguide will be synthesized.
