Microstrip‚ Stripline‚ and CPW Design Iulian Rosu‚ YO3DAC / VA3IUL‚ http://www.qsl.net/va3iul In the first years of microwave development the Rectangular Waveguide become the dominant waveguide structure largely because high-quality components could be designed using it. One of the main issues was its narrow bandwidth due to the cut-off frequency characteristic. Later‚ researchers try to find components that could provide greater bandwidth and possible miniaturization‚ and therefore they examined

Technology A new Approach to High-Power Energy Harvesting is proposed to convert mechanical to eleclterical energy based on reverse electrowetting [1] . This energy generates through a novel microfluidic phenomenon. Reverse electrowetting is a process by which liquid motion is converted into electrical energy. It can generate a power up to 103Wm−2‚ by this technology. Reverse electrowetting (REWOD) concept At first‚ The principle of electrowetting is defined in here. The shape of a liquid droplet

How to Find an Earth Fault On board Ships? Earth fault is considered very critical on board a ship. Some ships which operate at 440 V do not have any trip devices attached for a single earth fault. However when the operating voltage exceeds 3000V‚ it is mandatory to have a protection system which isolates when a machinery suffers an earth fault. How to find out an Earth Fault? The seriousness of the action to be taken on an Earth Fault depends on the part of the electrical system it affects. Conventional
