Mehrstrahlinterferenz und Beugung in abgeblendeten Parallelspiegel-Interferometern

The relations between multiple-beam interference and normal oscillation modes in a parallel-plate resonator are clarified in a preceeding paper. Based on experiments with cm-waves, here diffraction and shadowing effects are investigated for interferometers containing diaphragms before, between or behind the mirror-plates. It is shown, that the observed phenomena can be fully understood on the basis of the mode concept mentioned above.
