Abstract: The US military relies on communication devices to manage and control operations. It is important to find the susceptibility of friendly-force assets to insure command and communication in an often uncontrolled electromagnetic spectrum. Likewise, it is crucial to explore the enemys susceptibility. Simulation of electromagnetic devices is often performed in a high-frequency structural simulator (HFSS). However, the complete susceptibility analysis cannot be performed in HFSS due to computational limitations including multiple devices. For this reason, this research project proposes to investigate the characterization of the susceptibility of radio frequency (RF) systems to jamming systems using HFSS (to obtain the far-field radiation patterns) and MATLAB software (to perform the susceptibility characterization). Thus, an algorithm that uses both reciprocity and superposition principles was developed. As a proof of concept a simulation was performed in HFSS where the RF systems and the jammers far-field radiation patterns were simulated. The characterization of the susceptibility of RF systems was performed by obtaining 2-dimensional (2D) and 3-dimensional (3D) susceptibility areas.
