Could a micro-transmittting device, smaller than, say, a golf ball be employed to emit an ultra-narrow detectable beam, (e.g. 1mm) with range of one or 1.5 decimeter to 2 or less centimeter? The ...
How do you super impose two or more signals to occupy a fix area of space with the resultant summed wave?
Is it possible to super-impose two or more signals all sent from different directions as a standing wave with the resulting summed wave occupying a fix area of space that is also a complex area? Do ...
I'm trying to understand how can multiple radio stations transmit information just by transmitting using different frequency. The way I understand it all those different frequency waves add up to a ...
