Real-time 1D FDTD simulation of second harmonic generation in periodically poled lithium niobate (PPLN). The user watches a fundamental pulse propagate through a crystal and generate second harmonic ...

This repository implements a full-wave electromagnetic Digital Twin for a planar microstrip antenna array in a cross configuration, specifically designed to rigorously evaluate Direction of Arrival ...

Abstract: The implicit Finite-Difference Time-Domain (FDTD) methods represent a class of algorithms that alleviate or even eliminate the Courant–Friedrich-Lev (CFL) stability condition inherent in ...

Abstract: A novel finite-difference time-domain (FDTD) method based on Newton’s second law of motion and bilinear transform (BT) technique is presented for modeling electromagnetic (EM) wave ...
