Abstract

In this work we present novel coupling devices, in terms of feed-throughs and launchers, which are able to increase the efficiency of the electromagnetic power transmission along the propagation chain of guided wave radar (GWR) transmitters for level and interface measurement. The novel concepts are validated by 2D ¹COMSOL^® axisymmetric simulations which prove that the innovative design improvements are able to increase the electromagnetic efficiency by at least 6 dB. Such novel GWR level transmitters can improve the accuracy and the measurement range of the next generation of GWR level transmitters.
