| • | 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) |
| • | 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 |
