摘要：

We present data characterizing the optical properties of feedhom-coupled TES polarimeters useful for future CMB measurements. In this detector architecture, TES bolometers are coupled to radiation through superconducting microstrip to a planar ortho-mode transducer inserted into waveguide. Filters in the microstrip define the pass bands for the detectors. We will present measurements of the co-polar optical efficiency, the cross-polar isolation and the detector bandpass and compare these results to expectations from simulations.
