Comparative evaluation of absorbing boundary conditions using Green's functions for layered media

Aksun, M. İrşadi; Dural, G. (IEEE, 1995)

Absorbing boundary conditions are comparatively studied using the Green's functions of the vector and scalar potentials for multilayer geometries and general sources. The absorbing boundaries are introduced as additional ...
FDTD simulations of multiple GPR systems

Oǧuz, Uğur; Gürel, Levent (IEEE, 2003-06)

A multiple-GPR detection system was simulated. The main advantage of such a system was that it saves time by detecting both the transverse and the longitudinal positions of the target by a B-scan measurement, whereas the ...
Frequency responses of ground-penetrating radars operating over highly lossy grounds

Oğuz, U.; Gürel, Levent (IEEE, 2002)

The finite-difference time-domain (FDTD) method is used to investigate the effects of highly lossy grounds and the frequency-band selection on ground-penetrating-radar (GPR) signals. The ground is modeled as a heterogeneous ...
