Fast Analysis of Scattering by Arbitrarily Shaped Three-Dimensional Objects Using the Precorrected-FFT Method

-This paper presents an accurate and efficient method-of-moments solution of the electrical-field integral equation (EFIE) for large, three-dimensional, arbitrarily shaped objects. In this method, the generalized conjugate residual method (GCR) is used to solve the matrix equation iteratively and the precorrected-FFT technique is then employed to accelerate the matrix-vector multiplication in i...

New Basis Functions for the Electromagnetic Solution of Arbitrarily-shaped, Three Dimensional Material Bodies Using Method of Moments

We present two sets of basis functions, defined over a pair of planar triangular patches, for the solution of electromagnetic scattering and radiation problems associated with arbitrarily-shaped conducting/dielectric surfaces using the method of moments solution procedure and triangular patch modeling. The basis functions are constant over the function subdomain and resemble pulse functions in ...

New Basis functions for the Electromagnetic Solution of Arbitrarily-shaped, Three Dimensional Conducting bodies using Method of Moments

In this work, we present a new set of basis functions, defined over a pair of planar triangular patches, for the solution of electromagnetic scattering and radiation problems associated with arbitrarily-shaped surfaces using the method of moments solution procedure. The basis functions are constant over the function subdomain and resemble pulse functions for one and two dimensional problems. Fu...

Space-Time Recovery of Arbitrarily Shaped Wave-Packets by Means of Three Dimensional Imaging Technique

We study numerically and experimentally self-focusing dynamics of femtosecond light pulses. By demonstrating the potential of three dimensional imaging technique for quantitative recovery of complex (arbitrarily shaped) wave packets, we monitor space-time transformation dynamics of 150-fs light pulse, which undergoes self-focusing and filamentation in water. Peculiar spatiotemporal and spectral...
