A simultaneous shape and topology optimization method for designing patch antennas is discussed. The material distribution of a dielectric substrate is optimized using topology optimization concurrently as the metallic patch is optimized using shape optimization. The radiation amplitude in a specified mode at a selected frequency is chosen as the design objective and the resonance frequency is consequently...
Such home networking technologies as UPnP have become common for users to connect their devices at home. In this paper, we propose dynamic overlay topology optimizing content search (DOTOCS) that enables flexible content searches while optimizing P2P overlay networks. DOTOCS allows nodes to change their logical links to reach other nodes that have frequent data transfers in fewer hops, providing users...
We investigate how network parameters, the size of physical topology, and waveband capacity, affect the cost of the hierarchical optical path networks that utilize waveband protection.
