Analysis and design of smart electromagnetic structures
Smart Materials and Structures, 2008Use of ferroelectric materials to improve antenna performance is an area of active research. Applying an electric field across a ferroelectric used as the dielectric in an antenna enables tuning the antenna performance. Ferroelectrics also have coupled electromechanical behavior due to which it is sensitive to mechanical strains and fluctuations in ...

Electromagnetic Metamaterials—Promises, Design, and Applications
Quantum Matter, 2014Since the year 2000 metamaterials attracted much interest. Fancy metamaterial applications such as the “perfect” Pendry lens and invisibility cloaks provided a boost of electromagnetic research. We outline difficulties associated with metamaterial design and consider metamaterial structures which are promising for industrial applications which will be ...

Electromagnetic Design Solutions
1990The use of electromagnetic computer codes in industrial environment is first of all dedicated to the design of electric devices. It is also a good way of understanding the phenomena which are the basis of the operation of the device: fields, fluxes... The paper will focuse the analysis of the aspects of computer codes useful for design and optimization

Investigations On The Electromagnetic Performance Of Alternate Electromagnetic Barrel Designs
Eighth IEEE International Conference on Pulsed Power, 2005This paper presents the results of a comprehensive study performed to examine the effects of different design configurations on the critical design parameters which affect the performance of parallel rail electromagnetic launcher barrels. The configurations investigated were 1. Four different rail-design configurations, 2.

Collaborative design in electromagnetics
2007We present a system architecture and a set of control techniques that allow heterogeneous software design tools to collaborate intelligently and automatically. One of their distinguishing features is the ability to perform concurrent processing. Systems based on this architecture are able to effectively solve large electromagnetic analysis problems ...

Radomes are enclosures for antennas. Most radomes are hollow dielectric shells although some contain perforated metallic layers or metallic reinforcing structures. Radomes are used with large antennas on the earth’s surface to reduce wind loading and to prevent accumulation of ice or snow; these radomes usually have spherical contours.

Optimisation of electromagnetic design using HPCN
1998The development of HPCN and portable parallel implementations through BSP has encouraged developers and users of electromagnetic design software to address both the “grand challenge” problems and replace analysis of a design with synthesis.

The design of a clinical electromagnetic bone stimulator
Clinical Physics and Physiological Measurement, 1981The design and construction of an air-cored electromagnetic bone stimulator is described. The magnetic field waveform chosen has been based on that used for in vitro studies and is the one most commonly found in clinical practice. Detailed information on the circuitry involved, the waveforms and field strengths produced and the design of coils is ...

The economical design of direct current electromagnets
Proceedings of the American Institute of Electrical Engineers, 1911The design of an electromagnet for a given duty can as a rule be varied considerably, and while it is comparatively easy to design a magnet that will serve a certain purpose, it requires careful consideration to find the most economical design in any given case.
