Intrinsic Impedance Calculator of EM Waves

Intrinsic impedance defines the relationship between electric and magnetic fields in an electromagnetic wave. It is a fundamental concept in EM wave propagation and transmission.

EXAMPLE:

INPUTS:

• Permeability (u0) = 12.56 * 10^-7
• permittivity (E0) = 8.854 * 10^-12

OUTPUT:

• intrinsic impedance = 377 Ohm

Intrinsic Impedance Formula

An intrinsic impedance calculator for EM waves uses the medium’s electric permittivity ((\epsilon )) and magnetic permeability ((\mu )) to find the ratio of electric to magnetic field strength. This is crucial to understand wave behaviour in different materials like air (around 377 ohms) or waveguides.

Summary Understanding intrinsic impedance helps with EMC shielding, as mismatches between wave impedance and shield impedance cause reflections, preventing wave energy from penetrating. This calculator provides a fast and reliable way to compute intrinsic impedance, aiding both conceptual learning and exam preparation.
