Abstract :
The groove guide is a low-loss waveguide that was proposed by Tischer in 1963 as an alternative to classic waveguides. Its basic structure, can be divided into an inner and two outer region. The inner region exhibits a lower phase velocity. Hence, the electromagnetic field is concentrated in the inner region and propagates along the groove. In the outer regions, the electromagnetic field is eavnescent.
