Researchers developed a model showing the ability of reconfigurable intelligent surfaces to redirect the propagation of radio waves, which could improve the signal. A method to analytically express ...
Researchers at The University of Manchester's National Graphene Institute have introduced a new class of reconfigurable intelligent surfaces capable of dynamically shaping terahertz (THz) and ...
(a) Unit optimization process with a hybrid continuous-discrete PSO algorithm. The particulars of the yellow and green boxes in the optimization are elaborated in (b) and (c), respectively. (b) The ...
