In this paper, a one-third triangular resonator with two electric walls and two magnetic walls is discussed as a basic resonant element to realize wideband passive circuits. The resonator is fulfilled by taking out about one-third of an isosceles or equilateral triangular resonator of the substrate integrated waveguide (SIW) version and therefore, is called as one-third-mode substrate integrated resonator...
In this paper, a compact bandpass cross-coupled substrate integrated waveguide (SIW) filter with transmission zero is proposed. Using three triangular cavities as basic elements, a bandpass filter is designed and fabricated on a single-layer substrate with the standard printed circuit boards (PCB) process. This structure gives full expression to the advantages of compact SIW triangular cavity. Not...
In this letter, a novel single split-ring resonator (SRR), which is etched on the back side of a coplanar waveguide (CPW), is presented and discussed. Metallic vias are used to connect the single SRR to ground planes, which greatly improve the performance of the structure. A stop band filter based on this novel structure is simulated and fabricated. Simulated and measured results are in good agreement...
A six-port network based on coplanar waveguide (CPW) interdigitated structures is proposed and presented. Among these six ports, two are isolated ports and two are coupled ports. The left two contain an input port and a direct port. In this paper, the network is designed for dividing the power equally between the two coupled ports and the direct port, namely about 4.8 dB. The return loss is better...
In this paper, a novel planar magic-T using H-plane folded substrate integrated waveguide (FSIW) and E-plane substrate integrated waveguide (SIW) power dividers without narrowband slotline-to-SIW transition is proposed. Due to the symmetrical field in the FSIW, two equal in-phase outputs are achieved. The signal applied to the difference SIW port, is split by the middle metal ground into two out-of-phase...
This paper presents a preliminary study on target reconstruction based on scattering mechanisms, where primitives geometries are used to decompose complex targets and each primitive scatterer is recognized by recognizing its scattering features.
Due to the dynamic and anonymous nature of open environments, it is critically important for agents to identify trustful cooperators which work consistently as they claim. In the e-services and e-commerce communities, trust and reputation systems are applied broadly as one kind of decision support systems, and aim to cope with the consistency problems caused by uncertain trust relationships. However,...
Trust-based reputation system (TBRS) provides us an excellent decision-support tool for distributed environments. TBRS quantifies the trust relationships between entities based on the information that describes the entities' past behavior, so it is significant for TBRS to guarantee the quantity, the quality and the reliability of the collected information. In distributed environments, due to the lack...
In order to improve success rate of new product development, an intelligent decision support system based on multi-agent for new product development is presented. The dialogue layer, problem decomposition layer, control layer and problem solving layer in the decision process are studied; corresponding decision support apply modules are built based on the design idea of decision support system with...
An intelligent decision support system based on MAS for new product development is presented for enhancing the success rate of new product development. The dialogue layer, problem decomposition layer, control layer and problem solving layer in the decision process are studied; corresponding decision support apply modules are built based on the design idea of decision support system with multi-structure...
