ABSTRACT: In this paper we make a comparative investigation of the signatures of shock activities caused by geoeffective interplanetary coronal mass ejections (ICMEs) and magnetic clouds on the ...

A new antenna solution for 5G and 6G employs MEMS structures using standard CMOS technologies to create digitally tunable nanoscale capacitors within the CMOS layers of a chip along with the control ...

Magnetic reconnection is an important rapid energy release mechanism in astrophysics. Magnetic energy can be effectively converted into plasma kinetic energy, thermal energy, and radiation energy.

Abstract: A small magnetic loop antenna has been studied for underground operation in 920-MHz band considering the application of underground-to-aboveground communications. The antenna has two ...

The Fusion360 design of the step motor support as well as the STL file used to print it on my 3D printer. The Arduino program used to drive the step motor Some pictures of the final result. The ...

Generally, the biggest problem a new ham radio operator will come across when starting out on the high frequency (HF) bands is finding physical space for the antennas. For a quick example, a dipole ...

Have you ever heard of a theremin? It’s an obscure musical instrument that’s been around for nearly a century. It’s played without being touched, and it produces a unique, otherworldly sound. The most ...
