Characteristic Modes: Theory and Applications in Antenna Engineering, None
The characteristic mode (CM) theory is a relatively new topic in the antenna community. The great potential of the CM theory in antenna engineering has not been widely recognized until 2000. In this chapter, several well‐known modal analysis methods for particular antenna problems are reviewed first. It helps the readers have a preliminary knowledge about what modal analysis talks about. ...

The characteristic mode (CM) theory is a relatively new topic in the antenna community. The great potential of the CM theory in antenna engineering has not been widely recognized until 2000. In this chapter, several well‐known modal analysis methods for particular antenna problems are reviewed first. It helps the readers have a preliminary knowledge about what modal analysis talks about. It also illustratively shows how these modal analysis methods can help in practical antenna design. Next, we address the fundamental question: why the characteristic modes were proposed and what are characteristic modes? The primary features of the CMs are then followed. A history review for developments and applications of the CM theory in antenna engineering are also presented. Finally, we briefly introduce many CM variants for different radiation/scattering structures and materials. The details of these CM variants will be described in Chapters , , , .
Stator of a permanent magnet synchronous motor (PMSM) for electric vehicle driving is focused on as the research object. Six kinds of finite element models for winding are built, and compared with test results to elect the model consistent with the actual stator winding. This model established contributes to the reference of motor stator vibration characteristics analysis model. On the basis of this model, analyze the impact of winding, stator case and end cap on vibration character, and its reasons.
The Fisher information matrix determines how much information is given by a measurement about the parameters that index the underlying probability distribution. This paper assumes that the parameters structure the mean value vector in a multivariate normal distribution. The Fisher matrix is then a Gramian constructed from the sensitivity vectors that characterize the first- order variation in the mean with respect to the parameters. The inverse of the Fisher matrix has several geometrical properties that bring insight into the problem of identifying multiple parameters. The angle between a given sensitivity vector and the linear subspace spanned by all others determines the variance bound for identifying a given parameter. Similarly, the covariance for identifying the linear influence of two different subsets of parameters depends on the principal angles between the linear subspaces spanned by the sensitivity vectors for the respective subsets.<<ETX>>
Summary form only given. This paper described a Newton-Raphson method that accurately shifts a set of electrical network poles and transfer function zeros to more suitable locations in the complex plane to improve the harmonic voltage performance of a system. The descriptor system approach is used for the computer modeling of electrical networks of any topology and their subsequent modal analysis. The pole and/or zero shifts are carried out by appropriate changes in the system elements (e.g. capacitor and/or reactor banks). Eigenvalue sensitivity coefficients are used to help determine those element changes that are the most cost-effective and also to compute the Jacobian elements for the Newton method. These changes may be carried out without impacting the system operating point. Results are presented for a realistic system model ion order to show the potential applications of the method.
The purpose of this paper is to describe the procedure carried out to design a handset antenna using the Theory of Characteristic Modes. The antenna, which is based on the PCB resonance design concept, consists of a folded slotted PCB that is excited by means of a planar square monopole. This antenna is suitable for mobile terminals as it provides excellent wideband performance and omnidirecctional radiation patterns.
A novel type of spatial flexible micromanipulator is designed based on flexure hinges, which can realize the translational motion along the Z axis and rotations around X and Y axes. During the design, we use the bridge displacement amplifier as translational pairs to drive platform movement, with a flexure hinges instead of the traditional hinges. The magnification ratio of the bridge displacement amplifier is calculated by the method of the elastic analysis with consideration of rotational and translational stiffness. The simulation and analysis are carried out with ANSYS Workbench. The theoretical calculation and simulation error are 8.77%. The micro-operation platform is analyzed by static simulation and modal analysis. The results show that the micromanipulator has a large working space and strong anti - interference ability, with a fast dynamic response speed.
The authors' approach makes use of the fact that in many practical devices, the lasing spectrum is restricted to only a few longitudinal modes, either by virtue of high repetition rate or by an artificial spectrally selective element such as a distributed Bragg reflector. These lasers therefore render themselves more naturally, not to the fully-time-domain analysis, but to a time-frequency-domain approach. The model is applicable to a wide variety of realistic actively, passively and hybridly mode-locked structures, and takes into account both slow and fast nonlinearities in the active medium. With this model, we can describe, on the same footing, a wide variety of transient as well as steady-state regimes including CW lasing, fully or partially rendered mode-locking (ML), and more complex dynamics including self-pulsing and chaotic instabilities. In our approach, the lasing light is decomposed into a set of longitudinal modes of the realistic (open and inhomogeneous) cavity. We first apply the model to a Fabry-Perot passively mode-locked (F=100 GHz) laser; the resulting steady-state spectra agree well with distributed time- domain model (DTDM) simulations, whilst providing an increase of about an order of magnitude in computation speed. Next, the model is applied to colliding-pulse ML (CPM) lasers (F-200 GHz); as expected, all the "odd" modes die out during the first 1-2 ns of the transient regime and are suppressed by at least 20 dB in the resulting spectrum, which corresponds to a full repetition frequency doubling of the ML pulse train. We also apply the model to harmonic sub-terahertz mode-locking.
