摘要：
We have designed a single mode composite bolometer for the millimeter wave W band (75-110 GHz). The bolometer has greater than 75% absorptance across the W band. In this paper we report on tests of K band (18-26 GHz) scale models of the absorber and we describe a circuit model that can be used to predict the return loss of a wide range of absorber geometries.
