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 ...

Abstract 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 ...

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 brief ...
