	Studies performed during the last few years at different facilities have indicated that the emission of Cherenkov Diffraction Radiation (ChDR) can be exploited for a range of non-invasive diagnostics. The question remains of how to choose an optimal dielectric material and which radiator shapes give the most promising results. This contribution presents a semi-analytical framework for calculating the electromagnetic field of a charged particle beam, taking into consideration its interaction with surrounding structures. It allows us to directly compute ChDR at arbitrary probe positions inside the radiator. Several configurations will be discussed and presented, including flat and cylindrical radiators of various dimensions and electrical properties, as well as multilayer structures obtained by adding coatings of metallic nanolayers.

	Cherenkov-Diffraction Radiation (ChDR) appears when a charged particle moves in the vicinity of a dielectric medium with velocity higher than the phase velocity of light inside the medium. As the charged particle does not contact the medium, the emission of ChDR is a phenomenon that can be exploited for a range of non-invasive beam diagnostics. Experimental tests are underway on the Booster To Storage-ring (BTS) test stand at Diamond Light Source to explore the use of dielectric radiators as Beam Position Monitor (BPM) pickups by measuring the incoherent ChDR emission. In order to compliment the experiments on the BTS test stand, ChDR simulations have been performed using the Polarisation Currents Approach (PCA) model. This paper explores the PCA simulations for the BTS test stand, and the application for future diagnostics.
