4port microwave waveguide

Four-Ports Waveguide Microwave Functions

In this blog post we want to discuss about a S-Paramter of a waveguide. We know that in Microwave we use S-Parameter for descriping these deveices.

Waveguide Microwave Functions

Consider a waveguide having 4 ports. If the power is applied to one port, it goes through all the 3 ports in some proportions where some of it might reflect back from the same port. This concept is clearly depicted in the following figure.

For description of microwave device we use scattering matrix.

In Microwave device we work with power, because in this situation working with power is more easy.So for any microwave element first job we should do is analyzing S-Parameter. In next day i try share some S-Parameter from different waveguide. For more info see this link.
