    Abstract

    Response of an infrared (lambda = 10.6 mu m) dipole antenna-coupled bolometer fabricated at the center of the flat side of a hemispherical silicon immersion lens is presented. Predicted and measured antenna patterns as well as the ratio of power from the lens-side to the air-side are provided as a function of illumination F/#. The power-division ratio, Phi(lens)/Phi(air), shown to be given by the squire root of the lens dielectric constant, epsilon(1/2)(Si) = 3.4, for F/# larger than F/2 whereas as F/# decreases to F/1 the ratio increases to 5 due to off-axis features in the radiation pattern.
