FIG. 1.

(a) Experimental measurement setup. The two ports of an automatic network analyzer are connected to the diaphragm inside the circular waveguide to be measured. Section (i) is a standard coax-to-rectangular waveguide transition. Section (ii) is a rectangular waveguide to circular waveguide low reflection mode converter. Section (iii) is a circular waveguide section with a diaphragm inside (frontal view is shown in the picture above). Dimensions: , , , and . The thickness of the diaphragm is 0.35 mm. mode cutoff occurs at 11.80 GHz. The natural resonance frequency of the rectangular slot is close to 15 GHz. (b) Equivalent circuit for the middle section of the setup in (a). is the frequency dependent impedance of the scattered mode.

Transmission coefficient (dB) for the structure in Fig. 1. Note the presence of total transmission with low losses (0.7 dB) at 11.42 GHz and almost total reflection (transmission level is about −32 dB) at 11.80 GHz.
