abcd2y

Converts ABCD-parameters to Y-parameters.

Library

EngeeRF

Syntax

Function call

y_params = abcd2y(abcd_params) — converts ABCDparameters abcd_params The parameters of conductivities y_params.

Arguments

Input arguments

# abcd_params — 2N-port ABCD-parameters

+ 2N×2N×M array of complex numbers

Details

2N-port ABCDparameters specified as an array of complex numbers of the size on on , where represents the number of frequency points of 2N-port ABCDparameters.

The function assumes that the matrices of ABCD-parameters have different submatrices , , and :

Output arguments

# y_params — 2N-port Y-parameters

+ 2N×2N×M array of complex numbers

Details

2N-port Y-parameters returned as an array of complex numbers of the size on on , where represents the number of frequency points of the 2N-port Y-parameters.

Examples

Converting ABCD-parameters to Y-parameters

Details

We define the matrix of ABCD-parameters and convert them to Y-parameters.
