Expansion of Gaussian modes and analysis about the beam waveguide
Abstract
A beam waveguide was examined in terms of the interception efficiency, the scatter field, the reflection efficiency of the short circuit plate, and the expansion of the Gaussian modes. The beam waveguide was modeled as two curve mirrors, two plane mirrors, and a prime feed, and basic equations were defined for the interception and reflection efficiencies and the scatter field. It is shown that the radius of the mirror, the radius of the wave front, the amplitude distribution in the crosssection, the distance between the two curved mirrors, and the distance between the reflective point on the second mirror and the image of the plane shortcircuit plate can all be computed. A calculation is performed for the interception efficiency for an infinite radius wave front.
