This communication presents a design method for dual-polarized stacked frequency selective rasorber (FSR) with two wide transmission bands. In order to achieve three absorbing bands and two broadband transmission windows simultaneously in a wide operating frequency range, two similar lossy layers, a low-pass frequency-selective surface (FSS), and a dual bandpass multilayer FSS is cascaded from the top to the bottom. The low-pass FSS acts as the ground of the lossy layers to generate a high-frequency absorption band. The interaction between the dual bandpass FSS and two lossy layers results in low- and intermediate-frequency absorption bands. Two transmission windows are achieved when two transmission bands of the lossy layer coincide with those of the low-pass and dual-bandpass FSSs. The designed FSR has two wide −3 dB transmission bands with fractional bandwidths of 45.98% and 23.31% and three absorbing bands with fractional bandwidths of 81.11%, 13.67%, and 3.36% for absorptivity greater than 80%. A prototype of the proposed FSR is fabricated and good agreement between the simulation and the measurement is obtained.

SYP‐3343, (E)‐2‐(2‐((3‐(4‐chlorophenyl)‐1‐methyl‐1H‐pyrazole‐5‐yloxy)methyl)) phenyl)‐3‐methoxyacrylate, is a novel fungicide with broad‐spectrum and high activity against fungi. In this paper, radioactive pyraoxystrobin, labeled in the pyrazole ring system was achieved from 14C labeled 4‐chlorobenzoic acid through substitution, cyclization, and condensation, in an overall chemical and radiochemical yield of 44%. The chemical and radiochemical purity of the title compound was 98.5% and 98.2%, respectively. This labeled SYP‐3343 was used as a radiotracer for metabolism, toxicology, mode of action, and other environmental studies. Copyright © 2011 John Wiley & Sons, Ltd.
