An implicit finite-difference time-domain method in cylindrical coordinates is developed using the locally one-dimensional (LOD) scheme. The Sherman-Morrison formula is utilized to solve a cyclic ...

In this paper, the finite-difference time-domain method (FDTD) with convolutional perfectly matched layer (CPML) in 2-D cylindrical coordinate system is derived for the calculating of the lightning ...

In this paper, a model of the heterogeneous anelastic seismic wave problem is proposed in three-dimensional (3D) cylindrical coordinates. We use the velocity-stress formula to describe the realistic ...

Abstract: Cylindrical vector beams are considered one special class of optical vector fields as the axially symmetric beam solution to the full vector electromagnetic wave equation. In this chapter, a ...
