Propagation Constant Calculator

How to Use the Propagation Constant Calculator

1. Enter the characteristic impedance (Z₀) of the transmission line in ohms (Ω).
2. Enter the angular frequency (ω) of the signal in radians per second (rad/s).
3. Click the "Calculate" button to compute the propagation constant.
4. The results will display the attenuation constant (α), phase constant (β), and the propagation constant (γ).

Working Principle

The propagation constant (γ) of a transmission line is a complex number that represents the attenuation and phase change of a signal as it travels along the line. It is given by the formula:

γ = α + jβ

Where:

• α is the attenuation constant, which represents the loss of signal power per unit length.
• β is the phase constant, which represents the phase shift per unit length.
• j is the imaginary unit.

The propagation constant is important in the design and analysis of transmission lines, as it helps in understanding how signals propagate through the line.
