A compact V-band planar wideband bandpass filter based on Liquid Crystal Polymer substrates

Abstract: The move to higher frequencies has stimulated the development of the materials and integration techniques of the RF/microwave/millimeter (mm)-wave areas. Until now, materials commonly used at high frequency are either expensive or have inadequate performance. Liquid crystal polymers (LCPs), have attracted much more attention as advanced candidates as RF/microwave/mm-wave substrate materials for commercial wireless applications due to their combination of features and performance. In this paper, a compact V-band planar microstrip bandpass filter with sharp-rejection, low insertion-loss and wide-bandwidth based on the dual-mode ring resonator is proposed. The filter is fabricated on a LCP substrate by using standard processing technology. The proposed filter exhibits a return loss level better than 10 dB, an insertion loss of 5 dB, and a 3-dB bandwidth of 30%. The simulated and measured results are compared and agree well, which shows the promising potential of LCP laminates for flexible RF/microwave/mm-wave substrates.

The game analysis of negative externality of environmental logistics and governmental regulation

Abstract: This paper mainly discusses the negative externality problems involved in environmental logistics and the necessity of government regulation, and the government’s role in resolving negative externality. In the process of greenisation, as the allotment of interests after the internalisation of exterior cost is concerned, there have been a series of games among subjects of logistics systems, including game between enterprises and environment, game among enterprises and game between government and enterprises. Through the analysis of game model, we conclude that we should avoid rent-seeking behaviour and at the same time economic incentives based on market are the most effective way to resolve negative externality. Environmental logistics cannot only rely on the forces of the market. The government should play a greater role. The government should speed up the course of greenisation in China by broadening the dissemination of environmental logistics, formulating criteria for judging the degree of environmental logistics, offering financial subsidies on environmental logistics, and guiding the related enterprises in engaging themselves in the work of technology development.
