The miniaturized patch antenna with enhanced bandwidth based on reactive impedance surface and slotted parasitic patches

Autor: Zhi-Hao Mu, Jing-Nan Ma, Chang-Xing Chen, Ying-Juan Zhao

Publikováno v: Journal of Physics: Conference Series. 1792:012060

We presented a miniaturized patch antenna with enhanced bandwidth. Reactive Impedance Surface (RIS) was introduced instead of the traditional metal floor, and bandwidth enhancement is realized by loading slotted parasitic patches. The reference anten

New Controller Design in QCNN and the Synchronization with Chaotic System

Autor: De Zhi Niu, Kun Qu, Xu-Jing Wang, Hui Fu, Yan Ming Zhao, Chang Xing Chen

Publikováno v: Applied Mechanics and Materials. :359-364

Synchronization problem between QCNN (Quantum Cellular Neural Networks) and duffing system was studied in the paper. Not only one new controller with less parameters in QCNN was designed, but it was proved by Lyapunov function that output signal woul
