Abstract :
Dichroic Cassegrain mirrors have been constructed from waveguide stacked on a variety of lattices. Their performance in the transmission mode is discussed. Circular guide on an equilateral triangular lattice gave the best results. To improve the copolar patterns the structure was loaded with dielectric.
