Abstract
Electromagnetic Crystal structures have been used as sidewalls in special waveguides 30 to 40 GHz. This has the effect of substituting a high impedance surfaces in place of the normal conducting metal sidewalls. The objectives in so doing are to obtain uniform electric field across the width of the waveguide and to force the wave in the guide to adopt the nature of a TEM wave. Insertion loss of Ka Band waveguides has been measured. The measurements indicate that insertion loss is low. The dependence of transmission phase on the center frequency of sidewall resonance has been measured and indicates that tunable sidewall resonance will provide simple and low loss phase shifting systems.
