Review:
Finite Difference Time Domain (fdtd)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
The finite-difference time-domain (FDTD) method is a computational modeling technique used primarily to solve Maxwell's equations for electromagnetic systems. It discretizes both time and space domains to simulate the propagation of electromagnetic waves, making it a powerful tool in antenna design, microwave engineering, photonics, and other fields involving electromagnetic analysis.
