Helmhurts

This article details a method for solving the Helmholtz equation to model electromagnetic wave propagation, specifically for optimizing WiFi reception. The author discretizes the 2D domain into a grid, converts the partial differential equation into a system of linear equations, and solves it via matrix inversion. The process involves mapping 2D grid indices to a 1D vector for matrix construction. A web app is also mentioned. This is a technical tutorial related to computational physics and numerical methods for wave propagation.
