The antennas scatter light in proportion to the electrical signals they detect, allowing researchers to capture real-time cellular interactions with remarkable accuracy.
This reflectarray uses an electronically reconfigurable unit cell, consisting of an antenna and a reflecting circuit that provides 2-bit reflection phase shift. A general method for designing this ...
Most ham radio operators will build an antenna of some sort when they first start listening or transmitting, whether it’s a simple dipole, a beam antenna like a Yagi ... need a balun to reduce ...
