For example, the 2-way Wilkinson power combiner is able to combine two coherent in-phase input waves, but for two incoherent waves, it needs a resistor to dissipate the undesired wave propagation between the two input ports [2,3].
A perfect power combiner is impossible for incoherent waves of the same frequency, same polarization, and same mode, as it is against the law of conservation of energy.
The coherent waves are in the specular directions while the incoherent waves are in all directions from -[pi]/2 to [pi]/2.
It is noted that the incoherent waves arise only from the "propagating waves", i.e., for scattered wave [k.sub.x] [member of] [-[k.sub.0], [k.sub.0]] while for transmitted wave [k.sub.x] [member of] [-[k.sub.n+1], [[k.sub.n+1]].
