A linear stability analysis of the Rayleigh–Taylor instability RTI between two ideal inviscid immiscible compressible fluids in cylindrical geometry is performed. Three-dimensional 3D cylindrical as well as two-dimensional 2D axisymmetric and circular unperturbed interfaces are considered and compared to the Cartesian cases with planar interface. Focuses are on the effects of compressibility, g...

In order to manufacture short gap single Si nanowire (NW) field effect transistor (FET) by imprinting and transferring method, we introduce the method using Al2O3 sacrificial layer. The diameters of cylindrical Si NW addressed between Au electrodes by dielectrophoretic (DEP) alignment method are controlled to 106, 128, and 148 nm. After imprinting and transfer process, cylindrical Si NW is embe...

The vacuum expectation values of the field squared and the energy-momentum tensor are investigated for a scalar field with Dirichlet boundary conditions and for the electromagnetic field inside a wedge with a coaxial cylindrical boundary. In the case of the electromagnetic field perfectly conducting boundary conditions are assumed on the bounding surfaces. By using the Abel-Plana-type formula f...

y = ƒ(#). On the positive side of the ^-plane take the curve lying on this cylindrical surface and satisfying the condition z = P(x) ; on the other side take the curve lying on the cylindrical surface and satisfying the condition z = — N(x). We thus intercept between two curves a part of the cylindrical surface for which x is on (ab). It is not difficult to form a fair intuitive notion of this ...

It was proposed that perfect invisibility cloaks can be constructed for hiding objects from electromagnetic illumination [J. B. Pendry, D. Schurig, and D. R. Smith, Science 312, 1780 (2006)10.1126/science.1125907]. The cylindrical cloaks experimentally demonstrated [D. Schurig, Science 314, 977 (2006)10.1126/science.1133628] and theoretically proposed [W. Cai, Nat. Photon. 1, 224 (2007)10.1038/...

Plasma immersion ion implantation (PIII) into gearywindmill structures is simulated by the particle-in-cell (PIC) method in cylindrical co-ordinates. In cylindrical co-ordinates, the gearywindmill geometry becomes a periodic regular structure. An equal number of particles are placed inside the cell with the same angular and radial distance. The ion density represented by each particle is obtain...

This paper describes a small cylindrical display for an anthropomorphic agent that communicates with users in a threedimentional (3D) environment. Conventional displays for anthropomorphic agents are designed for a single user or a fixed viewing direction. We suggest a new small cylindrical display that is visible from the outside in any direction. Image data for the projector is calculated by ...
