Multi-stage distributed beamforming for distributed mosaic wireless networks is provided. Embodiments described herein present systems, devices, and methods that provide increased range, data rate, and robustness to interference and jamming. A distributed mosaic wireless network includes a transmitter, a receiver, and one or more distributed clusters of radios referred to herein as mosaics or relay mosaics. Each mosaic consists of several distributed, cooperative radio transceivers (e.g., mosaic nodes) that relay a signal sent by the transmitter towards the receiver. In some embodiments, a single-stage beamforming technique is implemented whereby the transmitter sends a signal to a first mosaic, which then relays this signal by beamforming to the receiver. In some embodiments, a multi-stage beamforming technique is implemented whereby the transmitter sends a signal to a first mosaic, which then relays this signal by beamforming to a second mosaic, which then relays this signal by beamforming to the receiver.

A planar sensor array capable of three-dimensional magnetic field sensing is disclosed. The sensor array may be utilized, for example, in connection with security inspections and detection of concealed electronics and contraband. Each sensor pixel may comprise a planar spiral inductor to measure a magnetic field of interest in a first dimension, a first Hall effect sensor to measure the magnetic field of interest in a second dimension, and a second Hall effect sensor to measure the magnetic field of interest in the third dimension.
