Microwave band gap and cavity mode in spoof-insulator-spoof waveguide with multiscale structured surface
Qiang Zhang, Jun Jun Xiao, Dezhuan Han +3
We propose a multiscale spoof-insulator-spoof (SIS) waveguide by introducing periodic geometry modulation in the wavelength scale to a SIS waveguide made of perfect electric conduc…
Collective dark states controlled transmission in plasmonic slot waveguide with a stub coupled to a cavity dimer
Zhenzhen Liu, Jun-Jun Xiao, Qiang Zhang +2
We report collective dark states controlled transmission in metal-dielectric-metal waveguides with a stub coupled to two twin cavities, namely, plasmonic waveguide-stub-dimer syste…
Capacity Analysis in Multi-Radio Multi-Channel Cognitive Radio Networks: A Small World Perspective
Xiaoxiong Zhong, Yang Qin, Li Li
Cognitive radio (CR) has emerged as a promising technology to improve spectrum utilization. Capacity analysis is very useful in investigating the ultimate performance limits for wi…
Transport Protocols in Cognitive Radio Networks: A Survey
Xiaoxiong Zhong, Yang Qin, Li Li
Cognitive radio networks (CRNs) have emerged as a promising solution to enhance spectrum utilization by using unused or less used spectrum in radio environments. The basic idea of…
