We have demonstrated the significant impacts of grating tapered sidewall profile on the subwavelength grating wideband reflector characteristics, when taking into account the practical fabrication process. Two different classes of wideband reflectors, referred to as Zero-Contrast Gratings (ZCG) and High-Contrast Gratings (HCG), are investigated in details(More)
Android is currently the most popular Operating System (OS) which is widespreadly installed on mobile phones, smart TVs and other wearable devices. Due to its overwhelming market share, Android attracts the attentions from many attackers. Reverse Engineering technology plays an important role in the field of Android security, such as cracking applications,(More)
Analyzing and researching the four elements of measuring process by using process method, it establishes the measuring system model of machine vision. It analyzes the component of measuring error, according to the analysis of measuring system model. It put forward a method of the error analysis of machine vision aiming based on the precision of edge(More)
