Plane Wave Calculator

This page provides a calculator for analyzing plane waves travelling in unbound materials in TEM (Transverse Electromagnetic) mode. It allows you to calculate key parameters such as phase velocity, wavelength, and wave impedance.

EXAMPLE:

INPUTS:

• Relative Permittivity (ε_r): 16
• Relative Permeability (μ_r): 4
• Frequency (f): 4 GHz

OUTPUTS:

• Phase Velocity (v_p): 3.75 x 10⁷ m/s
• Wavelength (λ): 0.009375 m
• Wave Impedance (η): 188.5 Ohm
