The University of Michigan has a class where we came up with an idea for + designed a 2mm x 2mm analog/digital chip and a MEMS chip, and got to go into the school's nanofabrication facility to help manufacture the chips. Everyone got to take one home. It was the most memorable class of my undergraduate career.

There's a Reuters article about this topic which states:

> Greenland’s ice sheet may have shrunk past the point of return, with the ice likely to melt away no matter how quickly the world reduces climate-warming emissions, new research suggests.

I've never worked on stealth aircraft, but energy has to travel from the transmitter, through the aircraft's radar cover, off the array itself, then get back through the cover and back to the receiver.

There are probably ways to filter for specific RF frequencies on the cover so only those in specific bands can get through, then the array itself might absorb some portion of the energy that gets through. The array also might be at an angle so waves are reflected in a different direction, or there might be radar absorbing material placed in specific spots that helps minimize reflections. I think the arrangement of elements in the phased array itself could also lead to reduced RCS at certain angles. Again these are just educated guesses, I would imagine the details are classified.
