Electromagnetic Design of a New Electromagnetic Planetary-Gear Machine
Applied Mechanics and Materials, 2013A novel brushless compound-structure permanent-magnet synchronous machine (CS-PMSM) based on the magnetic field modulation principle is proposed for hybrid electric vehicles. As the key part of the brushless CS-PMSM, the operation principle of the electromagnetic planetary-gear machine (EPGM) is investigated by analytical method.

Electromagnetic wave lenses and reflectors designed with transformation electromagnetics
2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014Lenses and reflectors are common devices in manipulating electromagnetic (EM) wave propagation and are largely utilized in radiation and receiving systems of electromagnetic engineering. The recently proposed significant concept of transformation electromagnetics provided an effective tool to design devices that could control the EM wave with desired ...

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.

Thin-layer electromagnetic absorber design
IEEE Transactions on Magnetics, 1989The design of effective broadband, thin-layer, electromagnetic absorbers for operation in the VHF/UHF regime has led to creation of design aids for custom-tailoring magnetic materials for this application. Theoretical analysis has implicitly determined the material configuration and electromagnetic parameter values of a single homogeneous layer of ...

Design Considerations for Electromagnetic Railguns
Journal of Pressure Vessel Technology, 2006Electromagnetic (EM) railguns are similar to powder guns in that both provide an accelerative force to the projectile, while accepting the resulting recoil impulse. They are designed to contain lateral and axial pressure. They must be capable of surviving the thermal environment to which they are exposed. Although there are similarities, there are also

Reducing SoC electromagnetic emissions by design
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008This paper deals with the design of power supply distribution network in CMOS System-on-Chips to reduce electromagnetic emissions. The main sources of both conducted and radiated emissions are pointed out and the most popular solutions for these problems are summarized. Based on that, the paper shows a new power supply network and grounding scheme that

Design issues of electromagnetic micropump
15th International Workshop on Research and Education in Mechatronics (REM), 2014Motivation of this paper is a high percentage of epidemic heart failure among the people all over the world where the highest rate of incidence of heart failure are recorded in industrialized countries. The purpose of this work was to design and construct a working micropump drive with a control system that implements a simplified hemodynamic cycle. In

Electromagnetic design of resonator-QWIPs
SPIE Proceedings, 2012Rigorous electromagnetic field modeling is applied to calculate the quantum efficiency (QE) of various quantum well infrared photodetector (QWIP) geometries. We found quantitative agreement between theory and experiment for linear grating coupled QWIPs, cross-grating coupled QWIPs, corrugated-QWIPs, and enhanced-QWIPs.
