Specific Absorption Calculation for Pilot Exposed to High Power Microwave

A simplified parallel finite difference time domain algorithm is brought out based on 1-ranked Debye equation by nonlinear levenberg-marquardt least-squares curve fitting method. A safety threshold with respect to spatial average and spatial peak specific absorption (SA) is proposed, a shielded cockpit glass construction is designed, and specific absorption calculation for pilot in an aircraft is carried out on 3D model with a scale of 1:1, which is electrically huge and very complex in geometry and electromagnetic parameters. The simulation tests show that the shielded cockpit is protective effective in the range of 0.3-6GHz by avoiding resonance frequency of human body and speedup ratio of the presented approach can compare with that of the conventional method.
