Creating a physically accurate CEM model of the REACH for global 21-cm cosmology

If you have a question about this talk, please contact Charles Walker .

I shall discuss gain pattern modelling with respect to observational 21-cm science. A focus will be placed upon how our knowledge of the physical structure of our instruments can impact their ability to successfully perform a detection of the 21-cm signature from the early universe. As an example case I shall discuss the REACH dipole radiometer, currently observing in the Karoo radio reserve South Africa, including the evolution of the construction and CEM models until this point and an overview of what is currently being done to calibrate and compensate for the gain pattern of the instrument.
