Transaction Line Propagation Constant Calculator.
This function will evaluate the propagation constants for a long transmission line whose properties are governed by the differential equation:
\[\frac{d^2V}{dx^2} = \gamma V\]From the above equation, the following formulas are derived to evaluate the desired constants.
\[\gamma = \sqrt{ z * y }\]\[Z_{\text{surge}} = \sqrt{ z / y }\]\[\alpha = \Re{ \gamma }\]\[\beta = \Im{ \gamma }\]
