Transmittance of MIM Waveguides Containing Semi-Circular Ring Shaped and Rectangular Ring Shaped Grooves

In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...

Ring-shaped lateral meniscus.

The existence of abnormal-shaped menisci has been long recognized. The presence of discoid menisci in the human knee is considered to be a congenital malformation with a very low rate of incidence except in Asian populations. Since the publication of Watanabe's Atlas, three types of lateral meniscal abnormalities are generally accepted: the complete and incomplete discoid, as well as the Wrisbe...

Ring-shaped exact Hopf solitons

The existence of ring-like structures in exact hopfion solutions is shown.

Two-curve-shaped biosensor using photonic crystal nano-ring resonators

We design a novel nano-ring resonator using two-dimensional photonic crystal (2D-PhC), for bio-sensing applications. The structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. These are configured by removing one row of air holes. The refractive index of sensing hole is changed by binding an analyte. Hence, intensity of the transmission spectrum...
