We present a physical optics analysis of the Heterodyne Array Receiver Program B-band (HARP-B) receiver for the James Clerk Maxwell Telescope (JCMT). Three sets of calculations are performed: 1. A Gaussian beam analysis to determine grid sizes for the Mach-Zehnder polarising interferometer. It is shown that an optimum grid size of 150mm clear diameter has little effect on the beam pattern and transmission of power through the system. 2. A Model of the HARP-B Imaging array is created using an ideal beam pattern for the corrugated feed. This produces an accurate beam pattern of minimal distortion. 3. The throughput and beam patterns for the whole HARP-B system are calculated. This produced beam patterns showing a high degree of symmetry with acceptable power coupling to the reflectors.
