ELECTROMAGNETIC-FORCE-DRIVING TYPE MEMS SWITCH USING HIGH PERFORMANCE NdFeB/Ta THIN FILM PERMANENT MAGNET
INTRODUCTION Because they have higher isolation and lower insertion loss compared to semiconductor switches, the last decade has seen the development of several types of MEMS (Micro Electro Mechanical Systems) switch. Many of these are electrostatically actuated and so need high drive voltages, limiting the initial gap between the contact points to a few micrometers [1-3]. Such small gaps betwe...
متن کاملModelling of Eddy-current Losses in a Surface-mounted Ndfeb Permanent-magnet Generator
In a surface-mounted sintered NdFeB permanent-magnet generator, the magnets are usually thin (typically 4 mm), and hence the armature reaction, due to the time harmonics in the stator currents, is high. NdFeB magnets are conducting (resistivity typically 1.6 μΩm) and experience eddy-current losses. Therefore, the combined eddy-current losses in the NdFeB magnets and a solid iron rotor may becom...
متن کاملSearch for possible radiation damage on a NdFeB permanent magnet structure after two years of operation
Recently there has been some concern about possible radiation damage due to ionizing particles present in high energy storage rings such as multi-GeV electrons, fast neutrons, or hard photons. Partial demagnetization has been observed on undulators after mis-steering of the injected electron beam. Our interest was focused to possible radiation damage of a permanent magnet insertion device durin...
متن کاملMeasurement of radiation-induced demagnetization of NdFeB permanent magnet material for ERL undulators
The note describes measurement of NdFeB permanent magnet (PM) material demagnetization induced by high-energy electron radiation. In experiments we compared N40 and N40SH grades from Stanford Magnets Company, which have different intrinsic coercive forces. Dimensions of the tested PM blocks were close to those that will be used for ERL undulator construction. It was found that depending on dire...
متن کاملDeep Adversarial 3D Shape Net
3D object understanding and reconstruction are important research questions in computer graphics and computer vision. In graphics, researchers tried to solve this question by breaking the shape down into separate shape parts (Huang et al. (2015)). This approach has achieved plausible results in shape synthesis. However, this requires pre-processing steps, including shape segmentation and resamp...
