The intrinsic impedance in a conductor is given by η = √(ωμ/2σ) x (1 + j).
The phase shift is represented by the 1 + j term.
In polar form it indicates 45 degree phase shift.

Electric and Magnetic Fields Phase Shift in an EM Wave
Electric and magnetic fields in an electromagnetic (EM) wave exhibit a phase shift, which is determined by the intrinsic impedance of the medium through which the wave is propagating.
Parameter determining the phase shift:
- Intrinsic Impedance: The intrinsic impedance of a medium is a characteristic property that influences how the electric and magnetic fields interact and propagate. In EM wave theory, the intrinsic impedance is denoted by the symbol Z and is calculated as the ratio of the electric field to the magnetic field in a wave.
Role of Intrinsic Impedance:
- Phase Shift: The intrinsic impedance of a medium determines the phase shift between the electric and magnetic fields in an EM wave. This phase shift is essential in understanding the behavior of the wave as it travels through different mediums.
- Relationship with Phase Constant: The phase constant, which represents the phase difference per unit length along the direction of propagation, is directly related to the intrinsic impedance. As the wave propagates, the phase shift between the electric and magnetic fields is determined by the intrinsic impedance and the phase constant.
Conclusion:
In summary, the phase shift in the electric and magnetic fields in an EM wave is primarily determined by the intrinsic impedance of the medium. Understanding this relationship is crucial in analyzing the behavior of electromagnetic waves in different environments.
