Traditional radio-based systems often suffer severe attenuation underground, as soil and rock absorb or scatter electromagnetic waves. By contrast, magnetic induction uses low-frequency magnetic ...

K-LOVE Radio’s recent upgrades with GatesAir in Montana and Utah show how modern transmitter design can deliver operational, ...

Wireless communication relies on radio waves, but reflections and interference can cause signals to fade or cancel out before reaching your device. This video explains the physics behind radio ...

Abstract: In this work, an amplitude-induced phase control method is proposed to achieve phase modulation by performing vector synthesis of two components with a tunable amplitude ratio. With a fixed ...

Abstract: Fluid antenna system (FAS) represents all forms of movable and non-movable position-flexible antenna system, and opens up the possibility of a new form of modulation schemes. In this paper, ...
