Abstract: To accurately simulate the thin layer of linear dispersive media, an improved 3-D finite-difference time-domain (FDTD) method is proposed. The inclusion of a weak conditionally stabilized ...
Abstract: Due to the inherent $\pi $ -phase constraint in phase unwrapping algorithms, the dynamic strain range of phase-sensitive optical time domain reflectometry ($\Phi $ -OTDR) is significantly ...
