Time Domain Transition Zone Diffraction on Convex Obstaclesrst-order transition zone diffraction, called the slope diffraction. The considered model is represented by its impulse response. Thanks to the introduction of some vital approximations of the expressions occurring in amplitude term and slope term of the impulse response; it can be given in a closed

Rigorous Modeling of Electromagnetic Wave Interactions with Large Dense Systems of Discrete Scatterebed. The method utilizes a periodic extension of the fast Fourier transform-based compression of the impedance matrix. The medium is modeled as a doubly periodic slab, infinite in two lateral directions, and composed of periodicity cells. The individual periodicity cell can be filled with periodical

A Hybrid Method for Solving 2-D Inverse Scattering Problemsoutine is used in which direct and expansion methods are utilized simultaneously to obtain more precise and fast reconstruction. In the first step, a coarse solution is achieved with the help of truncated cosine Fourier series expansion method. Then, with this solution as an initial guess for the se

Time-Reversal-Based Signal Processing Techniques for Ultra-wideband Electromagnetic Imaginghes employing acoustical or electromagnetic (EM) waves have been developed. One such approach is the time-reversal (TR) technique which has originally been introduced in acoustics and involves the retransmission of signals acquired by a set of transceivers in a time-reversed fashion to exploit the i

Advanced Imaging by Space–Time Deconvolution in Array GPRisition by elements of the array significantly increases the scanning speed. Such a GPR system with a single transmit antenna and a linear receive array has been developed in the Delft University of Technology. For online processing we propose an advanced imaging algorithm based on migration by regu

A TDFEM-Employed Temporal Second-Order Lagrange Interpolation for Three-Dimensional EM Radiation Pro and spatial expansion, respectively. This approach is motivated by goals of achieving computational efficiency and further applying to ultra-wideband (UWB) antenna simulation. Traditional TDFEM scheme is based on Galerkin’s method with a piecewise linear temporal expansion of the electric field. In
