Effective mass (m*) is defined as: where x, y, z are the directions in the reciprocal Cartesian space (2Ï€/A), En(k) is the dispersion relation for the n-th electronic band. The explicit form of the ...
Abstract: Finite-difference time-domain (FDTD) method combined with the recursive convolution technique is applied to compute lightning electromagnetic pulses (LEMP) for dispersive ground adopting ...
