As a typical manufacturing industry, the automobile industry has high requirements for quality management. Today, with rapid development of information technology, it is important to consider characteristics management in and whole life cycle products. Based on this perspective, an evaluation index system data big platform were established. This research guiding significance governments serve e...

In this work, a plasmonic right-angled waveguide bend and divider are proposed. Using the Transformation Optics (TO) approach transformation media of T-shaped obtained. Such with continuous refractive index realized help graphene in terahertz frequency range, key to effectively guiding surface plasmon polariton (SPP) propagation on 90 degree curves. Components such capability promising for THz ...
