Theoretical analysis and simulation results show that the theoretical analysis is basically consistent with simulation results when it is zero backlash  and does some theory research and dynamic analysis of backlash nonlinearity and system natural frequency and resonance frequency. First  and the error of theoretical analysis and simulation results is within 10%. Therefore  according to describing function to theoretically model the backlash nonlinear  it can be concluded that considering the transmission system theoretical analysis of backlash nonlinearity is feasible  the relation between describing function and the amount of backlash and input amplitude is analyzed  and it is much closer to the actual system with instructive significance. 2011 IEEE.   Effects of fabricated error on transmission performance of double screens cross loop slot FSS configuration (EI CONFERENCE) 会议论文  OAI收割 2006 7th International Symposium on Antennas, Propagation and EM Theory, ISAPE 2006, October 26, 2006 - October 29, 2006, Guilin, China 作者:  He B. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 This paper proposes that the inter-layer separation distance (ISD) and the unit cell aligning error (UAE) are used as main variables to study the transmission performance attenuation of the double layer FSS configuration. The numerical analysis model for ISD and UAE was established and also was used to simulate the cross loop slot cell FSS transmission performance by the finite element and periodic moment method program. The double layer cross loop aperture FSS configuration designed was used as the numerical model. As a result of the numerical analysis  it is shown that both ISD and UAE produce insertion transmission loss (ITL) and insertion phase distortion (IPD) directly. Furthermore  ISD results in much loss of the amplitude of the transmitted signal for the FSS than UAE. It is significant for the designer for the multiplayer FSS to assign the fabricated error of the FSS dielectric layers. The UAE introduces the insertion phase variation badly.
