Air filled circular waveguide calculator and formula for TE11 mode

An air filled circular waveguide calculator is a computational tool designed to help analyze electromagnetic wave propagation in circular waveguides operating in the dominant TE11 mode. By using the waveguide dimensions and operating frequency, the calculator applies standard electromagnetic waveguide formulas to determine key parameters such as cutoff frequency, guide wavelength and wave impedance. This tool is useful for understanding waveguide behavior and for designing microwave and RF communication systems.

EXAMPLE calculation:

INPUTS:

• Operating Frequency (f) in GHz = 3.5 GHz
• Circular waveguide diameter (d) = 8 cm

OUTPUT:

• Cut-off frequency (Fc) = 2.19 GHz
• Guide Wavelength in cm = 11.01
• Wave Impedance in Ohms = 484.37

Air filled circular waveguide formula

Summary: The circular waveguide calculator simplifies the evaluation of TE11 mode propagation characteristics by accurately computing cutoff frequency, guide wavelength and wave impedance using fundamental waveguide equations.
