Reportedly, levels of radiation have temporarily exceeded 1,000 micro sievert, which is twice the legal upper limit; but in many cases they have been little worse than an X-ray.
The evolution rule of the rare earth aluminum capacitor foil preparation process was investigated by means of bit etching, EBSD micro orientation analysis and X-ray method.
In this thesis, based on the requirement of azimuth scanning X-band phased array antenna design, micro-strip antenna array that has wideband characteristic is studied.
