Abstract: In order to realize the high speed and high-precision control of a maglev planar motor, a high-precision electromagnetic model is needed in the first place, which can also contribute to meeting the real-time running requirements. Traditionally, the electromagnetic model is based on analytical calculations. However, this neglects the model simplification and the manufacturing errors, w...
We report a method in the framework of surface wave holography to manipulate the electromagnetic wave on the metallic surface for realizing complicated electromagnetic wave transport functionalities in three-dimensional (3D) space. The method allows for direct determination of the metallic surface structure morphology for a given transport functionality, by means of writing desirable object inf...
A visualization system of spatial electromagnetic environment was designed and realized. The system realized 2D and 3D visualization of electromagnetic field with electromagnetic distribution situation, isograms, and propagation direction and path. The application result shows that the prototype system can provide the user an efficient visualization tool of spatial electromagnetic environment. ...
The switching device turn-on and turn-off process will produce high-frequency electromagnetic interference, based on the finite element method ANSYS software with powerful computing capabilities, has been widely used in complex electromagnetic field calculations. In this paper, ANSYS software to model and analyze the insulated gate bipolar transistor (IGBT) and quantitative distribution of elec...
This paper describes a new method for coupling ultrasound images with tree-dimensional electromagnetic data, to recover larger parts of the tongue during speech production. The electromagnetic data is superimposed on ultrasound images after spatial and temporal calibration. Successful fusion results are presented on various speech sequences. A complete setup for evaluation of the electromagneti...
In this paper, we give a review of the tensor method for treating the propagation of scalar and electromagnetic Gaussian Schell-model (GSM) beams. Partially coherent complex curvature tensor is introduced to describe a scalar astigmatic partially coherent GSM beam with twisted phase (i.e., twisted anisotropic GSM beam). A tensor ABCD law for treating the propagation of scalar twisted anisotropi...
The higher frequency transient signals generated as a result of a power system fault or disturbance provide the basis for an alternative approach to power system containing connectors and cables result in unsuitable operation of the system. However one major challenge is the need to ensure that the transients to be neutralized by electromagnetic compatibility (EMC) issues and cabling routes. T...
In order to solve reliability evaluation of life of electromagnetic valve of EMUs, this paper evaluates the life of electromagnetic valve under small sample size based on zero-failure data. Firstly, this paper selects the prior distribution of the failure probability, and then the posteriori distribution is obtained by using the Bayes method so that the Bayes estimation can be received under th...
