A Low-RCS 2D Multi-Layer Van Atta Array at X-Band
نویسندگان
چکیده
This paper presents a novel approach to reducing radar cross section (RCS) using 2D multi-layer Van Atta array based on the phase cancellation principle. By controlling of transmission lines wideband shifters, proposed can achieve significant RCS reduction at wide frequency range 8 GHz 11 GHz. Both theoretical calculations and experimental measurements were conducted evaluate performance with shifters. Results showed from various incident angles, demonstrating effectiveness design in achieving X-band.

Band engineering in a van der Waals heterostructure using a 2D polar material and a capping layer
Van der Waals (vdW) heterostructures are expected to play a key role in next-generation electronic and optoelectronic devices. In this study, the band alignment of a vdW heterostructure with 2D polar materials was studied using first-principles calculations. As a model case study, single-sided fluorographene (a 2D polar material) on insulating (h-BN) and metallic (graphite) substrates was inves...
متن کاملA Multi-Band Array For The Burbs
In the winter of 2002, I relocated my family from our small ranch in the southeast corner of Wyoming to the south Denver suburbs. For my hobby, it was a difficult relocation as I had to give up my antenna farm made of numerous towers, antennas and, in particular, my 4 square arrays for 40 and 80 meters. These arrays were used primarily for my own science studies regarding short and long path DX...
