Optimized Design of Multi-Layer Absorber for Human Tissue Surface

نویسندگان

چکیده

In this paper, the structure optimization scheme of multi-layer absorber on surface human tissue is designed. The uses graphite, foam and other materials to build a resistance loss layer. Solve electromagnetic parameters graphite through its characteristics, use equivalent transmission line theory calculate reflection coefficient. Establish objective function coefficient, genetic algorithm optimize design absorbing device. experimental results show that compared with Jaumann type three-layer absorber, coefficient optimized by in paper has decreased nearly 13 dB. From analysis error sensitivity, it can be concluded when material thickness within range ±0.005 mm, microwave absorption performance multilayer about 5%. Within range, guaranteed. sensitivity each layer indicate concentration have greatest impact absorber.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
