    "abstract": "SCUBA-2 is the next-generation replacement for SCUBA (Sub-millimetre Common\nUser Bolometer Array) on the James Clerk Maxwell Telescope. Operating at 450\nand 850 microns, SCUBA-2 fills the focal plane of the telescope with\nfully-sampled, monolithic bolometer arrays. Each SCUBA-2 pixel uses a\nquarter-wave slab of silicon with an implanted resistive layer and backshort as\nan absorber and a superconducting transition edge sensor as a thermometer. In\norder to verify and optimize the pixel design, we have investigated the\nelectromagnetic behaviour of the detectors, using both a simple\ntransmission-line model and Ansoft HFSS, a finite-element electromagnetic\nsimulator. We used the transmission line model to fit transmission measurements\nof doped wafers and determined the correct implant dose for the absorbing\nlayer. The more detailed HFSS modelling yielded some unexpected results which\nled us to modify the pixel design. We also verified that the detectors suffered\nlittle loss of sensitivity for off-axis angles up to about 30 degrees.",
