Abstract: We compare the technique of using the orbital angular momentum (OAM) of radio waves for generating multiple channels in a radio communication scenario with traditional ...

Abstract: This letter presents a triple-beam and triple-mode orbital angular momentum (OAM) generating metasurface comprising 16 × 16 units. Each unit can independently modulate x-polarized and ...

I tried the Bambu Lab $63 kit that lets you 3D print your own magnetic levitating toys complete with wireless power for their lights! It’s part of its Maker’s Supply initiative where it stocks ...
