UT Austin Engineers Design Next-Generation Non-Reciprocal Antenna
A newly built antenna doesn't have to listen to itself talk.
Usually antennas are as adept at receiving signals of a particular frequency as transmitting them. That's a problem because antennas end up listening to echoes of the signals they just broadcast, which slows down communications. Now scientists have built a specialized antenna that can transmit 50 times more strongly than it receives. The advance could improve antennas and may even help solar cells harvest more energy from the sun.

Makes me wonder there could be value to analogize influential texts to antennas. The intensity of "survival of the fittest" could count as a noise echo of Darwin's "The Origin of Species", for instance. Special design to separate receptive and emissive angles, reminds me of the text of John's Book of Revelations.
ReplyDeleteFull duplex antenna. Microwave waveguides have directional transitions, called a "magic T"
