A logical 1x2 reciprocal waveguide coupler.
Transmissions and reflections and backcoupling can be set using the properties to arbitrary values without any enforcement of passivity.
Properties dealing with tranmission: straight_coupling1, straight_coupling2 Properties dealing with reflection: reflection_in1, reflection_out1, reflection_out2 Properties dealing with back coupling: back_coupling
The default behaviour of the coupler model assumes symmetry that allows the permutations (out_1 with out_2) in the first place. If your component uses this symmetry, properties only have to be specified for in and out_1, the ones relating to out_2 will be assuming this symmetry.
In the second place the coupler model assumes symmetry that allows the permutation of output ports with input ports.
