Air-Filled Circular Cavity Resonator Calculator
Estimate the resonant frequency of an air-filled cylindrical cavity (TE₀₁₁ mode).
Using the formula:
\[
f_{011} = \frac{c}{2\pi}\sqrt{\left(\frac{3.832}{a}\right)^2 + \left(\frac{\pi}{d}\right)^2}
\]
where \(c \approx 3 \times 10^8\) m/s.
* Enter the cavity radius (a) and height (d) in meters.
