High precision structural Finite Element Analysis (FEA) results are required in the development of a remote image sensor. HperMesh and MSC. Nastran are employed in the image sensor structural FEA. This paper discusses some technical issues about the Finite Element (FE) modeling of the image sensor. In order to obtain authentic analysis results  the part-to-whole handling schema  i.e. handling method and research work is implemented in a small part of the model firstly and a revised method is used in the whole structural in succession  has been proposed. Some emphasis is mainly put on the FE handling of bolted joint  bearing and inter-element connection. The interface handling methods  such as CBEAM plus partial MPC bolted joint model  hybrid element bearing model and RBE3 beam-to-solid connection  have been produced and successfully implemented in the image sensor structural FEA. 2010 IEEE.

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.
