Direct-current component, high-order artifacts, and side lobe distortion provide serious drawbacks in the application of Fresnel zone plate coded imaging (ZPCI)
A novel design of out-of-plane grating couplers is proposed for coupling between silicon-on-insulator nanophotonicwaveguides and single-mode fibres. The coupler
We discuss jet production from an advection dominated accretion flow (ADAF) around a rotating black hole (BH) in an electromagnetic regime. An analytical expres
