The cross-strip imaging readout employs charge division, and centroiding, of microchannel plate charge signals detected on two orthogonal layers of sense strips to encode event X-Y positions and times. We have developed cross-strip detectors and fully parallel channel position encoding electronics. The front-end amplifiers utilize two 32-channel pre-amplifier ASICs that send signals to a full 6...

Flow features and forces of three-dimensional flapping foils are presented with aspect-ratio (AR) variations. The similitude rolling twisting kinematics is maintained across different ARs. An AR correction analogous to Prandtl finite-wing theory developed, enabling future use strip in the analysis design finite foils.

Closed-form expressions are obtained for the generating function of close-packed dimers on a 2M × 2N simple quartic lattice embedded on a Möbius strip and a Klein bottle. Finite-size corrections are also analyzed and compared with those under cylindrical and free boundary conditions. Particularly, it is found that, for large lattices of the same size and with a square symmetry, the number of di...

Sensing of gases is a promising area for applications of photonic systems operating in the mid-infrared spectral range. We present an infrared evanescent-field absorption gas sensor based on a silicon strip waveguide, which was specifically designed for CO2 sensing. We discuss finite element simulations that were used to design the strip waveguide and furthermore present experimental data of qu...

The alternate strip-based iterative substructuring algorithms are preconditioning techniques for the discrete systems which arise from the finite element approximation of symmetric elliptic boundary value problems. The algorithms presented in this paper may be viewed as simple, direct extensions of the two disjoint subdomains case to the multiple domains decomposition with interior cross-points...

We suggest an approach to grid optimization for a second order finite-difference scheme for elliptic equations. A model problem corresponding to the three-point finite-difference semidiscretization of the Laplace equation on a semi-infinite strip is considered. We relate the approximate boundary Neumann-to-Dirichlet map to a rational function and calculate steps of our finite-difference grid us...

The area of micro strip antennas has seen some inventive work in recent years and is currently one of the most dynamic fields of antenna theory. An overview of work done in the area of micro strip antennas is presented and several recent developments in the field are highlighted. In addition, new antenna configurations that improve electrical performance and manufacturability are described. Thi...
