There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

The use of silicon photonics has now enabled the creation of 60-GHz microwave waveforms with programmable amplitude, frequency and phase. Microwave waveforms with a large time–bandwidth product (TBWP) ...

Wave energy has long been seen as a promising source of clean electricity. The ocean is always moving, and that motion ...
