Introduction to Finite Difference Time Domain (FDTD) Method - SlideServe

When Metal Bars Teach a Wave Where to GoThis is a directional radiator built from several conducting bars. One bar is driven, the bar behind it acts like a reflector, and the bars in front act like directors, so the electromagnetic field is pushed forward instead of spreading equally in all directions.*Built with the finite-difference time-domain method, or FDTD. Maxwell’s equations are stepped forward on a Yee grid, so the electric and magnetic fields evolve directly in time and the wave patter
