...But microwave is not like laser energy where it is focused. Microwave can be beamed, but it does disperse over distance...
Microwave energy most certainly can be focused like a laser.
It’s called a Maser.
OK, I stand corrected. I had heard of Maser but frankly did not understand it.
Just read a little about it and realized I was at a site once. I got the tour of the VLA site in Datil, NM when they had the first 3 dishes operational. They were using cryogenic receivers then. Then came along the GASFETs.
