Rectangular Waveguide Breakdown Power Calculator

Estimate the maximum power a rectangular waveguide can transmit before breakdown.

Using the formula:
\[ P_{br} = \frac{a \, b \, E_{br}^2}{2 \, Z_0} \]
where \( Z_0 \approx 377\,\Omega \).

* Enter the waveguide width (a), height (b) in meters, and breakdown electric field \( E_{br} \) in V/m.

Step 1: Enter Waveguide Parameters

Waveguide Width, \( a \) (m):

Example: 0.1 m

Waveguide Height, \( b \) (m):

Example: 0.05 m

Breakdown Electric Field, \( E_{br} \) (V/m):

Example: 30,000 V/m (30 kV/m)
