WebOct 30, 2024 · A technique to synthesize a new category of radar cross-section (RCS)-reduction metasurfaces is presented. The appealing feature of the proposed technique is that by representing the generalized Snell-Descartes' law of reflection in the form of array factor, it unifies the two most widely studied and well-established modern RCS-reduction … The size of a target's image on radar is measured by the radar cross section or RCS, often represented by the symbol σ and expressed in square meters. This does not equal geometric area. A perfectly conducting sphere of projected cross sectional area 1 m (i.e. a diameter of 1.13 m) will have an RCS of 1 m . Note that for radar wavelengths much less than the diameter of the sphere, RCS is independent of frequency. Conversely, a square flat plate of area 1 m will have an …
In-Band Radar Cross-Section Reduction of Slot Antenna Using ...
WebThe most important method is to reduce the radiation cross-section (RCS) of a vehicle by designing the shape of the object and eliminating the unnecessary edges and sharp points (Knott et al., 2004). Another effective method is utilizing electromagnetic wave absorbing materials, especially in the microwave region. WebDec 14, 2024 · In this letter, a novel design strategy for a linearly polarized metasurface antenna array that integrates low scattering and well-behaved radiation is proposed. First, a metasurface is designed with 180° reflection phase difference under orthogonal normal incident waves. By introducing L-feeding patches along the orthogonal direction to the … low town road
