    The goal of this project was to create development board to test the capabilities of the RP2040 microcontroller in RF applications. The RP2040 has many capabilities that make it a good candidate for a low cost intermediate frequency (IF) data acquisition board. The firmware takes full advantage of the programmable I/O (PIO) and direct memory…

    A multifocal metasurface lens for continuous wave doppler radar was designed for a 4×4 K band patch array antenna. The metaparticle structure used was a 2 layer dogbone structure for its simplicity and its proven control of the phase of an incident wave. This work was an exploration into the feasibility of developing an easily…
