Wireless sensor networks (WSN) are becoming increasingly promising in practice. As the predeployment design and optimization usually unpractical random deployment scenarios, global optimum of WSN’s performance is achievable only if topology dependent self-organizing process acquires overview WSN, which boundary most important. The idea this paper comes from fact that contours break on geometrical WSN discrete sampling systems real environments. By simulating a diffusion form, end point...

When the satellite is on orbit, it will periodically enter illuminated areas and shadow areas, which produce an alternating temperature field. The field cause thermal deformation thermally induced vibration. These responses have a greater impact more flexible SAR antenna. Therefore, this paper adopts method of combining theory simulation to conduct integrated control modeling analysis large deflection antenna considering space environment structural heat dissipation under 4 typical working...

Abstract In this paper, the full‐wave volume‐surface integral equation (VSIE), modified surface integration (MSI) method, and ray‐tracing process are combined to efficiently analyze electromagnetic performance of receiving antennas enclosed by radome with variable thickness. The mutual interactions between antenna considered coupling VSIE MSI in a nested iterative manner, which is applied model complex composite conductor‐dielectric structure, while method used deal large‐size dielectric...
