Implementation Details
The element is defined by the following s-parameters matrix:
$$s(f)=\begin{bmatrix} \frac{Z_c}{Z_c+2R_0} & \frac{2R_0}{Z_c+2R_0} \\[0.3em] \frac{2R_0}{Z_c+2R_0} & \frac{Z_c}{Z_c+2R_0} \end{bmatrix}$$
Where \(Z_c\) is defined as:
$$Z_c=\frac{i}{1\cdot 2\pi \cdot f \cdot C}$$
Where \(f\) is the frequency and \(C\) is the ‘capacitance’ property. \(R_0\) is the internal characteristic impedance. If the element is disabled, it assumes the value of \(C\) is zero (open circuit).
