Hello. We're in the age of the high speed computation. Personal computer clock speed is on the order of GHz and scientist looks for a way to raise the speed up to THz class. I've read this from newspaper and got some question. I've learned in class that radiation effect becomes severe as electrical frequency becomes higher and higher on the conductor. Although I have no calculation of how much energy is lost to radiation, I guess this kind of loss is observable and maybe huge. Maybe industry already faces this side effect. How is this effect controlled or minimized? Engineers should consider this effect..
