The fast increase of users in existing mobile networks requires more base stations (BSs) to bear more communication traffic.Future heterogeneous network is considered to be a promising candidate architecture to meet the demands of wireless networks under scarcity of radio frequency (RF) resources.In this paper, we present a multi-mode relay (MMR) m

In this article the author presents a point of view which she eksfolierende toner considers central to understanding the difference between prevention - associated with the traditional discourse of public health - and health promotion, an idea in connection with which proposals are now being presented for rethinking and redirecting public health pr

We report on an ultra-compact, low loss and broadband TM-pass polarizer, which is constructed by two Tubing interleaved subwavelength-gratings (SWGs) waveguides inserted in the center of the strip waveguide on a silicon-on-insulator (SOI) platform.The device structure is optimally engineered to support Bloch mode for fundamental TM polarization onl
