An increasing number of contemporary detector designs incorporate materials with finite conductivity to achieve various objectives, including enhanced robustness, improved spatial precision, and operation at high fluences. Prime examples of these are the (multi-gap) Resistive Plate Chambers (MRPC), Resistive Silicon Detector (RSD), and resistive small pad Micromegas. The uninterrupted advancements of simulation tools, like Garfield++, have played a pivotal role in developing and understanding particle detector technologies. Therefore, it is imperative that these modeling tools accurately reflect the technological progress made in designs incorporating resistive elements. This seminar explores a universally applicable method for numerically computing the signals induced in these structures by utilizing an extended version of the Ramo-Shockley theorem. Various strategies will be presented for characterizing a wide range of resistive technologies spanning the spectrum of resistive particle detectors, from MRPCs to MPGDs to solid-state detectors. These methods could be employed to provide a deeper understanding of existing structures and inform the design of the next generation of particle detectors tailored to the specific requirements of future High Energy Physics (HEP) experiments.
