Hello dear all,
I am looking for the answer of following basic issues that I encountered (could not understand) while trying to simulate strip-slot waveguide converter.
why is the number of trial modes shown by mode expansion monitor and Eigensolver analysis are different for the same structure? (can check for strip and slot waveguide here coupler3.fsp (4.2 MB) and strip slot strip coupler.lms (338.4 KB) ).
If I launch a fundamental mode in a uniform waveguide which supports multimodes, will power be preserved in fundamental mode or fraction of power be transferred to higher order modes?
If the mode is TE of TM is indicated by the TE/TM fraction. But sometimes mode looks like TE though TM fraction is greater than TE fraction
Thanks in advance.
