Frequency-Domain and Spatial-Domain Reconfigurable Metasurface.

The recently proposed digital reconfigurable metasurfaces make it possible to manipulate electromagnetic (EM) waves flexibly. However, most existing reconfigurable metasurfaces can only exhibit a relatively single performance in the spatial domain. Here, we propose a general frequency- and spatial-domain reconfigurable metasurface (FSRM) that can manipulate the EM waves and realize reconfigurable functions in multifrequency bands.

Characterization of the life cycle of the tick Haemaphysalis tibetensis under field conditions in Qinghai-Tibet plateau.

The tick Haemaphysalis tibetensis Hoogstraal is found uniquely in the Qinghai-Tibet plateau of Tibet and Gansu of China. Not much is known of this tick. Therefore, in this study we investigated the life cycle of H.
