Abstract:
A metamaterial for separating an electromagnetic wave beam is disclosed. Two kinds of man-made microstructures are attached on a substrate of the metamaterial. The first man-made microstructures each have a principal optical axis parallel to a first electric field direction, and the second man-made microstructures each have a principal optical axis parallel to a second electric field direction. The metamaterial comprises a first region and a second region. The first man-made microstructures in the first region have the largest geometric size and the first man-made microstructures in other regions increase in geometric size continuously in a direction towards the first region; and the second man-made microstructures in the second region have the largest geometric size and the second man-made microstructures in other regions increase in geometric size continuously in a direction towards the second region.
Abstract:
Embodiments of the present disclosure relate to an impedance matching component and a hybrid wave-absorbing material. The impedance matching component is disposed between a first medium and a second medium, and comprises a plurality of functional sheet layers. Impedances of the functional sheet layers vary continuously in a stacking direction of the functional sheet layers, with the impedance of a first one of the functional sheet layers being identical to that of the first medium and the impedance of a last one of the functional sheet layers being identical to that of the second medium.

Abstract:
The present disclosure provides a unipolar MIMO antenna, which consists of a plurality of unipolar RF antennae. Each of the unipolar RF antennae comprises a metal sheet and a feeder line. The metal sheet is enchased with a metal microstructure thereon, and the feeder line and the metal sheet are connected in a signal communicative manner. The unipolar MIMO antenna of the present disclosure breaks through the framework of the conventional antenna design and eliminates the complex design of the impedance matching network to ensure miniaturization of the antenna. Thereby, the antenna can be used in a wireless apparatus having a small size, a high transmission efficiency and a high isolation degree among antennae and can satisfy the requirement of a low power consumption in the design of modern communication systems. Additionally, the present disclosure further provides a bipolar MIMO antenna and a hybrid MIMO antenna.

The present invention discloses a business operation mode based on artificial-intelligence+legal-affairs+business-affairs. AI is the empowerment, legal-affairs' main-body, business-affairs' framework. AI characteristics lie-in two-learning or two-experts, including Internet-of-human, Internet-of-things, Internet-of-intelligence; applying AI computer-program to control or improve business-quality. AI+legal-affairs innovation lies-in new-brain or new-procedures, using contract to authorize AI's basic-role in judicial-affairs. Identification or adjudication is made by deep-learning and reinforcement-learning, both priorities accept. Experts separately verify evidence or fact, video-trial, mediate then arbitrate. Expert-database complements expert-system each-other, explains algorithm, and promotes reconciliation. Financial-experts control credit-limit and perform-contract through guarantee insurance. AI+legal-affairs+business-affairs characteristics lie-in two-lines or two-supports, applying AI to verify the credit of excellent business-subjects or business-quality, and control to improve business-process. To improve business-quality, focuses are on AI-health, AI-teaching, AI-traffic, or other public-services.
Abstract:
Photocatalysis is a promising technique for remediation of indoor air pollution. The present invention focuses on the enhancement of the effectiveness of the photocatalytic process by the introduction of artificial roughness on the interior reactor surface. Artificial roughness elements on the catalytic surface enhance the turbulence intensity close to the catalytic surface. The enhanced turbulence intensity translates to an increase in the mass transfer of airborne contaminants to the catalyst surface, improving the efficiency of photocatalysis.
