—In this paper, we propose a method to use 1-D dielectric slabs, instead of metallic Frequency Selective Surfaces (FSSs), to produce Partially Reflective Surfaces (PRSs) with positive reflection phase gradients. The structure is realized by a single kind of dielectric substrate. It is modeled as cascaded transmission lines and then analyzed by virtue of the(More)
In this historical cohort study, 236 patients with primary rheumatoid arthritis were treated with the tumor necrosis factor inhibitors, etanercept or infliximab (n = 80), or by conventional methods (n = 156).
