We present a neural network architecture to determine the volume and complex permittivity of grain stored in metal bins. The neural networks output the grain height, cone angle and complex permittivity of the grain, using the input of experimental fi

Electromagnetic inversion systems require that the experimental data be calibrated to the computational inversion model being used. In addition, accurate prior information provided to the inversion algorithm leads to higher-quality images. For some a

The contrast source inversion (CSI), a robust technique for solving inverse electromagnetic scattering problems, has previously been applied to data from multiple frequencies in two primary ways: frequency-hopping solves one inverse problem at a sing

An implementation of a PDE-based Contrast Source Inversion (CSI) algorithm using a hybrid Open MP-CUDA parallel programming model is presented for the acceleration of microwave imaging. The CSI algorithm uses a time-harmonic discontinuous Galerkin me
