High- Radio-Frequency Structures Using One-Dimensionally Periodic Metallic Films

High-Q structures are very interesting theoretically, and very important practically, for a variety of engineering applications in communication systems. We address the issue of designing a thin-film metal structure of reflectivity higher than the intrinsic reflectivity of the bulk metal itself. We study a finite array of planar conducting layers of arbitrary thickness periodically placed an ar...

Active cooling by metallic sandwich structures with periodic cores

We review the thermal characteristics of all-metallic sandwich structures with two dimensional prismatic and truss cores. Results are presented based on measurements in conjunction with analytical modeling and numerical simulation. The periodic nature of these core structures allows derivation of the macroscopic quantities of interest—namely, the overall Nusselt number and friction factor—by me...

Low porosity metallic periodic structures with negative Poisson's ratio.

Auxetic behavior in low porosity metallic structures is demonstrated via a simple system of orthogonal elliptical voids. In this minimal 2D system, the Poisson's ratio can be effectively controlled by changing the aspect ratio of the voids. In this way, large negative values of Poisson's ratio can be achieved, indicating an effective strategy for designing auxetic structures with desired porosity.

Surface-Wave Suppression Using Periodic Structures

The objective of this paper is to design impedance surfaces for the solution of the problem of electromagnetic compatibility of antennas. In a recent paper, corresponding surfaces were used to reduce coupling between antennas located on a plane. These surfaces were made artificially, e.g., by loading a conducting surface with corrugations. The design of the impedance structure is done for a giv...

Experimental study of sensitivity enhancement in surface plasmon resonance biosensors by use of periodic metallic nanowires.

We have experimentally confirmed sensitivity enhancement of a nanowire-based surface plasmon resonance (SPR) sensor structure. Gold nanowires with periods of 200 and 500 nm were fabricated, respectively, by electron-beam and interference lithography on a gold/SF10 substrate. Sensitivity enhancement was measured to be 44% compared with a conventional thin-film-based SPR structure for nanowires o...
