Electromagnetic Bandgap(EBG) structures are periodic metal-dielectric material posing the property of suppressing surface wave propagation in a frequency range.
EBG structures are extensively used material in reducing mutual coupling effects between patch antennas[2-3].

Experimental Materials. 4, 4'-diaminodiphenyl ether (AR) and 4, 4'-diaminodiphenyl sulfone(AR), 4, 4'-diaminodiphenylmethane(AR) and 4, 4'-Thiodianiline(AR) were purchased from Aldrich chemical Co. and used without further purification.
The weight loss of polymers before 160 OC reflected the moisture content of the material.
Those with highest weight loss before 160 OC could be a relative hydrophilic material that may be suitable to be used in RO.

The Analysis of Generation and Transformation of Strip Warps Jian Qin a, Qingdong Zhangb, Peicheng Zhangc Mechanical Engineering School, University of Science and Technology Beijing, Beijing 100083 China aE-mail: mechmath@126.com, bE-mail: zhang_qd@me.ustb.edu.cn, cE-mail: me818@me.ustb.edu.cn Keywords: Strip; Warp; Gutter; Curl; Residual strain; Transformation Abstract.
The material is assumed to be isotropic and elastic.
(13) If it is taken into account the deformation due to the weight of strip, the non-uniform distribution of initial strain and the cutting free boundary, the modified coefficient is introduced (about 0.25 which changes with material data).
