ƒ transmission : calculates normalized transmission ƒ getelectric (and getmagnetic) : retrieves : By default it automatically unfolds data with the correct symmetries Most electromagnetic field data from the simulations is a 3 (2D) or 4 (3D) dimensional matrix. ...
Power normalization and energy conservation with the TFSF can be non-intuitive. For example, you may find that power transmission measurements depend on the size of the source. It is also possible to find situations where power measurements are greater than 100%. While this may be non-int...
However, since the “time” and “time_signal” properties of sources are important for calculating the sourcepower, sourcenorm, and the normalization for the transmission functions, care must be taken with source normalization. In particular, in most cases, nonorm option should be used. Auto ...

Only the transmission to the ‘out1’ port is plotted because the MMI is symmetric. We see that around half of the power is transmitted to each output port, but the MMI can be optimized further. The electric field at the output port can be visualized thanks to the monitor we placed earl...
