A bstract In theories with a warped extra dimension, composite fermions, as e.g. the right-handed top quark, can be very strongly coupled to Kaluza-Klein (KK) fields. particular, KK gluons in presence of such fields become broad resonances, thus remarkably modifying their experimental signatures. We have computed pole mass and width gluon, triggered by its interaction quarks, well prediction fo...

We present a semianalytical scheme for the design of broad-angle multichannel metagratings (MG), sparse periodic arrangements loaded conducting strips (meta-atoms), embedded in multilayer printed circuit board configuration. By judicious choice periodicity and angles incidence, scattering off such MG can be described via multi-port network, where input output ports correspond to different illum...
