What are cavity resonators? A rectangular waveguide cavity has the dimension $22.86$ $\mathrm{mm} \times 10.16 \mathrm{~mm} \times 15 \mathrm{~mm}$. Calculate the resonant frequency for the $\mathrm{TE}_{101}$ mode. Consider air as dialectic.

Solution:

A resonator is a device that exhibits resonance at a particular frequency called resonance frequency. Cavity resonators are constructed by sharing both ends of a guide.

When the canty is excited through probes, with a signal frequency equal to the resonant frequency decided by waveguide dimensions, a resonance is …
