Determination of Phase Shift Constant and Intrinsic Impedance in Lossy Medium
What are the key parameters needed to determine the Phase Shift Constant and Intrinsic Impedance in a lossy medium with specific values?
Phase Shift Constant:
Attenuation Constant (α):
The formula to calculate the α is α = ω√(μr/εr) tan⁻¹( tanδ). Given the values of frequency, permeability, permittivity, and loss tangent, we can substitute them into the formula to find α.
Phase Constant (β):
The formula for β is β = ω√(μrεr). By substituting the provided values, we can determine β.
Combining α and β gives the Phase shift constant γ = α + jβ.
Intrinsic Impedance:
The intrinsic impedance (η) in a lossy medium is calculated using the formula η = (jωμ/α)(1+j) where μ is the permeability of the medium. By substituting the given values, we can find the intrinsic impedance in the lossy medium.
