Air-Filled Circular Cavity Resonator Calculator

    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.

    Step 1: Enter Resonator Parameters

    Example: 0.05 m

    Example: 0.1 m

    Formula: \[ f_{011} = \frac{c}{2\pi}\sqrt{\left(\frac{3.832}{a}\right)^2 + \left(\frac{\pi}{d}\right)^2} \] with \( c \approx 3 \times 10^8 \) m/s.
