The angular distributions of muons from Upsilon (1S,2S,3S) to mu+mu- decays are measured using data from proton anti-proton collisions at sqrt (s)=1.96 TeV corresponding to an integrated luminosity of ...

We put forward an optically transparent microwave absorber based on a conformal broadband metamaterial, which shows high angular stability. Our absorber is a double-layer sandwich structure mainly ...
