An R switch with a stator and a rotor with three paths wherein a central, straight interconnection is constructed as step transformers and formed bar-like by recesses incorporated laterally in the in the steps of the transformers in order to lower the low frequency limit of the HF signals which can be transmitted.

R switch

With the help of the millimeter wave measurement system, the surface impedance is determined by means of one or a plurality of resonators with very high three dimensional resolution when there are relatively large resonator openings in the millimeter wave range. By means of this, structures with measurements of {fraction (1/10)} the resonator openings can be solved with no trouble (FIG.,).
