The relation between incident voltage matrix , reflected voltage matrix and S matrix for a microwave network:

Electronics and Communication Engineering (ECE) : Microwave Communication - Quiz(MCQ)

[v-] = [s] [v+].

[s] = [v] [v-].

[v-] [v] = [s].

[v+] = [s] [v-].

Correct Answer : Option (A) : [v-] = [s] [v+].

Explanation : S parameter for a microwave network is defined as the ratio of reflected voltage wave to the incident voltage wave. When represented in the form of a matrix, reflected voltage matrix is the product of S parameter and the incident voltage wave at that port.
