What is the impedance of a rectangular waveguide wave

The impedance of a rectangular waveguide is not a single value; it varies by mode and frequency. For the dominant TE10 mode, the wave impedance is approximately 377 Ω (η) multiplied by the ratio of the guide wavelength to the free-space wavelength. ​​What Is Waveguide Impedance?​​ ​​Waveguide impedance isn’t some abstract idea—it’s a ​​measured value […]
