Abstract

A novel reflector made from the highly unidirectional structure of the three-phase interdigital transducer resulting in high reflection coefficients from extremely short transducer lengths is presented. Such a reflector only requires a single phasing component. The dependency of the reflection on the unidirectionality yields frequency tuning capabilities via the phasing component. Such a reflector was fabricated and measured to determine the reflection from a short transducer. Two independent methods for determining the reflection coefficient from the measurements are presented.
