title = "CSEM modelling using high order FDTD on the nonuniform grid",
abstract = "We present a high-order finite-difference time-domain (FDTD) modelling method on nonuniform grids for 3D controlled-source electromagnetics (CSEM). The coefficients for our high-order finite-difference scheme are adaptively computed over the staggered nonuniform grid by inverting a Vandermonde matrix system. This crucial procedure greatly improves the accuracy compared with the 2nd order staggered scheme on nonuniform grid, which possesses only 1st order local truncation error due to centered differencing on non-equal spaced grids. Numerical examples demonstrate that our method is highly accurate and efficient.",
