Rectangular Cavity Resonator Calculator
Calculate the resonant frequency of an air‑filled rectangular cavity resonator using:
\[
f_{mnp} = \frac{c}{2}\sqrt{\left(\frac{m}{a}\right)^2+\left(\frac{n}{b}\right)^2+\left(\frac{p}{d}\right)^2}
\]
where \(c=3\times10^8\) m/s, and \(a\), \(b\), \(d\) are the cavity dimensions.
* Enter the cavity dimensions in meters and the mode indices (m, n, p). For example, TE101 corresponds to (1, 0, 1).
Step 1: Enter Cavity Dimensions and Mode
Example: 0.05 m
Example: 0.025 m
Example: 0.1 m
Example: TE101 → (1,0,1)
