The sensitivity of the He6-CRES experiment is limited by frequency-dependent oscillations in the signal-to-noise ratio (SNR) observed in initial data. We model these oscillations as a result of various reflective components in the apparatus forming a multi-mirror Fabry-Perot cavity. Electromagnetic simulations of key RF components along with a model for the reflections will allow us to mitigate the issue of irregular SNR. Prior work has characterized several elements of our radio-frequency (RF) system in simulation, namely the quarter-wave polarizer and circular-to-rectangular waveguide transition. In this project, we construct a model and simulation of the full He6-CRES waveguide system, including simulating CRES radiation in a decay cell, enabling a more comprehensive computational study of the observed SNR variations.
