Abstract: In this work, using the generalized Boltzmann equation of Zadehgol [Phys. Rev. E 94, 023316 (2016)2470-004510.1103/PhysRevE.94.023316] a lattice Boltzmann time-domain (LBTD) method is proposed. The time-domain methods, such as the finite-difference time-domain method (FDTD), have been… read more here.
