A linear polarization conversion coding metasurface (MS) is proposed for the radar cross section (RCS) reduction of an object. The designed MS has both wideband RCS and high efficiency mirror reflection in different frequency bands. cells are arranged according to 1 bit sequences, characteristics verified by emulations experiments. simulation results indicate that 01/10 MSs possess greater than 10 dB 9.5-13.9 15.2-20.4 GHz, less sensitive under normal incidence. experiment show achieved...
A flexible, dual-broadband, and polarization-insensitive coding metasurface is proposed to manipulate electromagnetic (EM) scattering in microwave frequency band. The 1 bit units "0" "1" are formed by the Pancharatnam–Berry (PB) phase based on same-sized meta-atoms with different orientations. layout of obtained through genetic algorithm (GA). simulation results indicate that this communication can achieve more than 10 dB radar cross section (RCS) reduction range 9.26–12.87 14.84–19.35 GHz...
A dual-broadband and high-efficiency reflective linear polarization converter based on an anisotropic metasurface is presented. The device consists of two symmetrical, double-slotted metallic split-rings one criss-cross structure, a dielectric layer, completely ground. exhibits four resonances can near-perfectly convert x- or y-polarized incident waves into cross-polarized in the frequency ranges 9.38–13.36 GHz 14.84–20.36 GHz. conversion ratios (PCRs) bands are 98.21% 99.32%, respectively....
Poly(glycerol–sebacate) (PGS) is an elastomeric biodegradable polyester that could be used as drug carrier. We have previously prepared PGS implants doped with 5-fluorouracil (5-FU-PGSs) and found 5-FU-PGSs exhibited initial burst of 5-FU release during in vitro degradation. The synthesis temperature time are two the most important reaction conditions for polymer synthesis. Therefore, order to establish a controllable drug-release manner, we series 5-FU-PGS 2% weight under different...
