[SOLVED] simulation with impedance or admittance elements in ADS

[tyenergy]

convert admittance to impedance

Hi, everyone, I have a question about simulation using impedance or admittance elements in ADS.

I have already obtained the admittance matrix, in my case, it is a symmetrical 3*3 matrix, which can be written as
[ Y11,Y12,Y13;
Y12,Y11,Y13;
Y13,Y13,Y33];

then I convert these admittance parameters into an equivalent circuit model as shown in the well-known Waveguide Handbook , section 6.1.

the circuit element in this equivalent circuit model can be expressed as

Xa = Y11+Y12;
Xb = -Y13+Y12;
Xc = Y13;
Xd = Y33+Y13;

my question is how to simulate this circuit in ADS, because I can only find capacitor and inductor in ADS, but in my case, Xa,Xb,Xc,Xd are not purely capacitors or inductors, the element value will change to positive or negtive in different frequency, as in most of microwave problem.

Does anyone know how to simulate this kind of circuit in ADS?

I have solved this problem.

use the ABCD matrix representation of the shunt and series element and choose the data item in ADS
