Electromagnetic (EM) wave tunneling through an epsilon-negative (ENG) waveguide has been realized when it paired with mu-negative (MNG) waveguide. The ENG waveguide is imitated by a hollow metallic waveguide which operating below cutoff frequency. The MNG waveguide is implemented by standard waveguide filled with square split resonate rings (SSRRs). The dimensions of the MNG waveguide differ from...
In this study, anti-inflammatory effect of coumarin of Angelicae dahuricae (CAD) and mechanism of its actions were studied. Experiments of mouse ear swelling induced by croton oil in mice, increased capillary permeability induced by glacial acetic acid in mice and rat paw swelling induced by carrageenan were used to observe the anti-inflammatory effect of CAD. ELISA was used to measure prostaglandin...
The coupling characteristics between a composite right/left-handed transmission line (CRLH TL) with lumped-elements and a conventional right-handed transmission line (RH TL), is studied. It is theoretically shown that tight coupling is obtained when the product of the average permittivity and average permeability is negative (epsiv macr ldr mu macr < 0), at the same time the CRLH TL is still in...
