Abstract
A novel plate waveguide has been designed in order to act as a low dispersion thermal buffer for application in flow metering. The proposed waveguide consists of a series of thin flat rectangular metallic plates which can behave as waveguides with limited dispersion. Extensive modeling based on the finite element method has been carried out to study the proposed waveguide design. A prototype waveguide has been built in order to carry out transmit-receive experiments in a water tank which have shown that, without backing on the transducer or impedance matching on the radiating face, it is possible to detect a signal through these waveguides. Preliminary results are encouraging, however, there is still much design optimization is required to make this device work for a given application.
