We study light transmission and reflection from an integrated microresonator device,formed by a circular microresonator coupled to a bus waveguide,with an embedded S-shaped additional crossover waveguide element that selectively couples counter-propagating modes in a propagation-direction-dependent *** overall shape of the device resembles a“taiji”symbol,hence its *** Lorentz reciprocity is preserved in transmission,the peculiar geometry allows us to exploit the non-Hermitian nature of the system to obtain high-contrast unidirectional reflection with negligible reflection for light incident in one direction and a significant reflection in the opposite direction.

对非感染大鼠和感染大鼠,在腹腔注射两性霉素B或两性霉素B加利福平后进行了血清浓度测定。两性霉素B的血清浓度在人接受该药治疗时,是易于达到的。动物接受二种药物时的两性霉素B血清浓度始终高于单独接受两性霉素B时的血清浓度。过去未曾证明两性霉素B和利福平联合应用对播散性念珠菌病有协同作用。本文在体内实验中,采用完善建立的大鼠播散性和致命性念珠菌病模型,利福平对两性霉素B的增强作用被明显地证实。这种增强作用是由于协同作用,还是由于二者联合时两性霉素B的血浓度增高,尚有待阐明。

In this paper,layered periodic foundations(LPFs)are numerically examined for their responses to longitudinal and transverse modes in the time and frequency *** different unit-cells,i.e.,2-layer,4-layer,and 6-layer unit-cells,comprising concrete/rubber,concrete/rubber/steel/rubber,and concrete/rubber/steel/rubber/lead/rubber materials,respectively,are taken into ***,the viscoelasticity behavior of the rubber is modeled with two factors,i.e.,a frequency-independent(FI)loss factor and a linear frequency-dependent(FD)loss *** the extraction of the complex dispersion curves and the identification of the band gaps(BGs),the simulations of wave transmission in the time and frequency domains are performed using the COmSOL *** parametric studies evaluate the effects of the rubber viscoelasticity models on the dispersion curves and the wave transmission for the longitudinal and transverse *** results show that considering the rubber viscoelasticity enhances the wave attenuation ***,the transverse-mode damping is more sensitive to the viscoelasticity model than its longitudinal *** 6-layer unit-cell LPF exhibits the lowest BG,ranging from 4.8 Hz to 6.5 Hz.
