Microwave photography aims to unveil the form and trajectory of microwaves during their propagation, akin to capturing images of electromagnetic waves in motion. The process involves capturing a visual representation of radio frequency (RF) waves using an RF receiver in the following manner:
a) The receiver comprises 2D square RF sensors that meticulously measure the amplitude and phase of the electric field at each grid point.
b) During the imaging process, a cell phone is actively engaged in a call and positioned atop the receiver.
c) Utilizing the collected near-field data grid, a three-dimensional depiction of the electromagnetic waves is subsequently generated via our proprietary FMA algorithm. This intricate 3D image not only illustrates the progression of the waves over time but also reveals the geometric intricacies of their propagation.
