: Optimizing how signals reach your phone through urban "clutter."

: This describes how waves (like radio or light) travel through space or materials. It is governed by Maxwell’s equations, which define how the electric field ( E⃗modified cap E with right arrow above ) and magnetic field ( H⃗modified cap H with right arrow above Electromagnetic Wave Propagation, Radiation, an...

: This occurs when a wave hits an object or a rough surface and "bounces" off in multiple directions. This is the principle behind radar technology and why the sky appears blue (Rayleigh scattering). Mathematical Foundation
