This letter addresses the performance degradation of reflectarrays (RAs) in practical operation due to aperiodic arrangement and mutual coupling between units, and proposes a reflection-coefficient ...
Abstract: Vertically transverse isotropic (VTI) media are widely present in the Earth's crust, particularly in reservoirs; therefore, accurately characterizing crustal stratigraphic features is ...
This project is a frequency measurement tool based on the Raspberry Pi Pico and the RP2040 microcontroller. It uses the PWM hardware to count edges on two input signals—one is the test signal, and the ...
