... Isn't it possible to focus any sort(frequency) of EM wave, at least in theory?
in theory, with "metamaterials", yes. in practice this is akin to the perfect invisibility cloak problem, full of devilish details... a full spectrum Superlens for any EM freq would be quite handy indeed :) best regards,
