ANCHOR-FDTD is a browser-native 2.5D FDTD electromagnetic simulator powered by WebGPU. It runs the full Maxwell’s equations update loop on your GPU — no install, no backend.
Requires WebGPU. Chrome 113+ or Edge 113+ on desktop. Safari and Firefox support is experimental. If the simulator doesn’t load, your browser likely doesn’t support WebGPU yet.
An interactive tool for building intuition about dielectric resonator antennas — modes, coupling, and the size–bandwidth tradeoff, all live in your browser.
