    Analysis of Dynamic Performance of Magnetic Field Modulated Gear by Liu Meijun, Bao Guangqing, Hou Chenchen, Zuo Zhengpu, Liu Mingmin

    Published 2017-01-01
    “…But its stiffness is low,which will lead to the transient oscillations undergoing the torque of prime motor is disturbance or the velocity changes.Based on the analysis of the basic principle of magnetic gear,a magnetic field modulated gear is designed,whose transmission ratio is 5. 5,and the performance of the magnetic gear with different structures is analyzed by using the electromagnetic field finite element method. A structure type with the highest efficiency is selected,in the iron core of high speed mover of selected gear by introducing damping winding with closed loop,in the process of transient oscillations,the current will be induced in the damping winding,which will produce damping electromagnetic torque can inhibit the mechanical vibration of transmission shaft and maintain the stability of system. …”

    Asymptotic Analysis of Transverse Magnetic Multiple Scattering by the Diffraction Grating of Penetrable Cylinders at Oblique Incidence by Ömer Kavaklıoğlu, Roger Henry Lang

    Published 2011-01-01
    “…We have presented a derivation of the asymptotic equations for transverse magnetic multiple scattering coefficients of an infinite grating of penetrable circular cylinders for obliquely incident plane electromagnetic waves. We have first deducted an “Ansatz” delineating the asymptotic behavior of the transverse magnetic multiple scattering coefficients associated with the most generalized condition of oblique incidence (Kavaklıoğlu, 2000) by exploiting Schlömilch series corresponding to the special circumstance that the grating spacing is much smaller than the wavelength of the incident electromagnetic radiation. …”

    Multi-ray channel modeling for programmable wireless environments in the terahertz band by Wenyu LUO, Hechao LIU

    Published 2019-07-01
    “…Terahertz communication system based on programmable wireless environment allowed programming customization of electromagnetic wave propagation in the most suitable ways for different wireless devices.It could not only improve serious fading,interference and non-line-of-sight problems,but also significantly enhance the security and privacy of the system.The channel modeling of terahertz wireless communication in programmable wireless environment was focused.Firstly,a multi-ray channel model for terahertz-band programmable wireless environment was established based on ray tracing technology as well as the propagation model of line-of-sight and non-line-of-sight.Then,based on the established propagation model,reflection coefficient,the broadband channel capacity under the water-filling power allocation algorithm and the RMS delayed extension were further studied.The simulation and analysis results show that the programmable wireless environment greatly reduces the influence of path loss and multipath fading in terahertz wireless transmission through active interference in electromagnetic wave transmission,improves the transmission capacity of terahertz communication system,which provides a reference for the later design of terahertz communication system,especially indoor terahertz communication system.…”
