Radiofrequency (RF) coils are used to transmit and receive signals in magnetic resonance (MR) systems. Optimized RF coil design has take into account strategies maximize the performance by choosing sizes geometry for achieving best signal-to-noise ratio (SNR). In particular, conductor radiative loss contributions strongly affect SNR value, with first mainly playing a role low-field MR systems e...

Numerical simulation of three-dimensional (3D) seismic wavefields forms the basis research on migration methods 3D data based wave equations. Because precision wavefield extrapolation determines imaging accuracy to a certain extent, it is very important study how enhance forward modeling wavefields. Thus, we build an optimized staggered-grid finite-difference (SFD) method with high two-dimensio...
