Power recorded across the observation vertical lines, comes negative.
We are launching a pulse in the designed resonator and trying to get Normalized transmission v/s wavelength for designed structure. Pulse is having central wavelength of 1.5 um and 2D transverse half width as 1.5 um. Issues and queries which we have are as follows
(1) After completion of simulation, when we go to analyzer file, observational vertical line L3 is showing power with negative values. We are getting negative value of power across L3 when calculating power corresponding to each wavelength in observational area analysis under Analyzer window. We have observed that whenever observation line record/sense the signal propagating either in negative X or Z direction, it gives negative value of power. Should we only note the magnitude of power only ignoring the negative sign in these cases?
(2) In order to get power at particular wavelength for particular port, We note the value of power corresponding to observation line placed at that port in observational area analysis under Analyzer window. Are we correctly doing this? is this the way to get the power at particular port?
(3) How do we get the raw data of power spectrum corresponding to each observational line placed against each port in the design?
For reference we also attached design file.
