Thin Absorbing Structure for All Incidence Angles Based on the Use of a High-impedance Surface
نویسنده
چکیده
It is shown that thin mushroom layers (high-impedance surfaces realized as regular arrays of small patches at a small distance from a metal surface) can be used as radar-absorbing structures whose performance does not change with the incidence angle for TM-polarized waves. The key role of the vias connectors between the patches and the ground plane is explained, and potential performance demonstrated in examples. © 2003 Wiley Periodicals, Inc.

Analysis and Design of Thin Planar Absorb- Ing Structure Using Jerusalem Cross Slot
A detailed analysis and design of thin planar absorbing structure using Jerusalem cross slot (JCS) is presented in this paper. Based on uniplanar compact high-impedance surface characteristics, the resistance loss material layer can be directly attached to the surface of JCS structure, thus absorbing electromagnetic waves effectively. The improved design is characterized by its wider bandwidth ...
متن کاملEffect of Corner Bluntness on Energy Absorbing Capability of Non-circular Metallic Tubes Subjected to Axial Impact
The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...
متن کاملEnhanced methanol sensing performance of oblique deposited WO3 thin films
Methanol (CH3OH) is a colorless liquid with a mild odor. The wide ranges of applications, toxicity and clinical implications of methanol have made necessary to develop reliable and high-performance methanol sensors. In this paper, WO3 thin films were deposited on SiO2/Si substrates by e-beam evaporation technique under normal and oblique angles and then post-annealed at 500 °C with a flow of ox...
متن کاملInvestigation of extinction spectra of THTS Mn thin films and comparsion with discrete dipole approximation simulation results
In this work, the extinction spectra of the nano-structure of the Tilt Helical and Stair-like Towers of Mn thin films were obtained using discrete dipole approximation (DDA) simulation for both s-and p-polarization at two incident light angles of 10°, and 60° at different azimuthal angles for the there samples with different tilt. Obtained results are compared with the experimental optical exti...
متن کاملThin Absorbing Screens Using Metamaterial Surfaces
Metamaterial surfaces can be conceptualized by 2-dimensional periodic arrangement of many small flat inclusions on an otherwise homogeneous host surface. Electromagnetic properties of such metamaterial plates, which can indeed be regarded as frequency-selective surfaces, are influenced by the shape and geometry of these inclusions. When a metamaterial surface is closely placed above a perfectly...
