Conversion formula for electric and magnetic fields

Conversion formula for electric and magnetic fields

The electric and magnetic field conversion formula using the free-space wave impedance of 377Ω applies only to far-field plane waves (EMC radiated nuisance, antenna far-field), and is not available for the near-field (coils, IF magnetic fields, near-field probes, near areas of shielded chambers). 377Ω ...
