S-Converter
S-Matrix Converting Module called in abbreviation S-Converter or SMCM is a software module provided by QWED designed to:
•
calculate S-matrix of a multiport structure composed of multiports of known S-matrices (so called to embedding operation)
•
calculate S-matrix describing a part of the structure when the S-matrices of other parts and the entire multiport structure are known (so called to deembedding operation)
Partition of a microwave circuit can be done for various reasons. Here are some practical situations providing a rationale for such an operation:
•
parts have separate functions and design of each of them separately is simpler
•
electromagnetic simulation of the entire structure would be impractical from the point of view of computer time or/and memory
•
different parts of the structure can be calculated more effectively by different software packages like for example QW-3D and QW-V2D
•
in the process of optimization of the structure the optimization variable(s) affect only a part of the structure
