A FDTD algorithm for the analysis of short optical pulse second harmonic generation in dispersive media

Second harmonic generation in transition metamaterials

“…In order to verify analytical predictions obtained by the undepleted field approximation, and to analyze the second harmonic wave generation inside the nonlinear transition layer in detail, Maxwell's equations were solved using the finite difference time domain method (FDTD) using a uniaxial perfectly matched layer (UPML) as a boundary condition [27][28][29]. Here relation between displacement vector and electric field is determined as…”
