Researchers developed a microscopic theory in which intra-valley, finite-momentum pair-density waves generate the Kekulé ...

Abstract: In this work, a method for increasing the efficiency-bandwidth product of an electrically small antenna (ESA) by using spatially discrete traveling-wave modulation (SDTWM) is introduced.

Abstract: Index modulation multiple access (IMMA) is a promising sixth-generation (6G) technique to prominently improve the spectral efficiency, energy efficiency, system performance, and support ...
