Time-Domain BLT Solver for Electromagnetic Coupling to Cables and Circuits

We propose to develop time-domain electromagnetic coupling effects software based on the MTL formulation for analyzing UWB radio frequency (RF) signal effects on electronics located inside semi-enclosed cavities, such as personal computers, buildings, vehicles and aircraft. The time-domain MTL solver software will be able to investigate computationally intensive electromagnetic coupling effects on shielded cables including the effects of large apertures and re-radiation off the cables over the frequency range of 200MHz to 10GHz. Our approach will use a time-domain BLT based transmission-line solver to compute fields that propagate along multi-conductor transmission lines. We will use FFT-based algorithms to accelerate the computations on the transmission lines allowing for solution of problems involving large numbers of transmission lines. Additionally, we will provide an interface for advanced circuit solvers for analyzing interactions with complex circuitry connected to the transmission lines. Time-domain BLT formulations for handling cavities and apertures will also be developed and validated as part of this effort. A graphical user interface (GUI) will be designed specifically for the purpose of decomposing a complex electromagnetic network using the principles of electromagnetic topology and interfacing directly with the MTL coupling effects computational engine.
