Analysis and Simulation of Energy Leakage for the Surface-Wave Waveguide Based on Tunable Impedance Cells

The Applied Computational Electromagnetics Society Journal (ACES) (2016)

Yong-Hong Zhou Xing Chen Zhangjie Luo

Controlling energy leakage is of great importance for users of surface-wave waveguides (SWGs) because it determines the propagating efficiency of surface waves. In this paper, a novel theoretical analysis of the energy leakage for these two types of SWGs is proposed, and the effects of some key parameters to the leakage such as the path width of the SWG and effective impedance of cell and incident angle are discussed more deeply. To verify the theoretical method, a model of the SWG consisting of 30 × 30 impedance-tunable cells driven by TM surface waves, whose impedance ranges from j370 ? to j780 ? according to our previous measurements, is simulated in HFSS. The simulation results are in good agreement with the theoretical ones, demonstrating that the leakage is inversely proportional to the width of the SWG and an increase of effective impedance of the guided path; furthermore, by using the impedance-tunable cells, the multi-functionality of the SWG is illustrated. The analyzing methods can be a guide for designing other SWGs without energy leakage, and as an inspiration for more complex SWG applications.

A Temperature Compensation Method for Piezo-Resistive Pressure Sensor Utilizing Chaotic Ions Motion Algorithm Optimized Hybrid Kernel LSSVM

Sensors (2016)

Ji Li Guoqing Hu Yong-Hong Zhou Chong Zou Wei Peng

A piezo-resistive pressure sensor is made of silicon, the nature of which is considerably influenced by ambient temperature. The effect of temperature should be eliminated during the working period in expectation of linear output. To deal with this issue, an approach consists of a hybrid kernel Least Squares Support Vector Machine (LSSVM) optimized by a chaotic ions motion algorithm presented. To achieve the learning and generalization for excellent performance, a hybrid kernel function, constructed by a local kernel as Radial Basis Function (RBF) kernel, and a global kernel as polynomial kernel is incorporated into the Least Squares Support Vector Machine. The chaotic ions motion algorithm is introduced to find the best hyper-parameters of the Least Squares Support Vector Machine. The temperature data from a calibration experiment is conducted to validate the proposed method. With attention on algorithm robustness and engineering applications, the compensation result shows the proposed scheme outperforms other compared methods on several performance measures as maximum absolute relative error, minimum absolute relative error mean and variance of the averaged value on fifty runs. Furthermore, the proposed temperature compensation approach lays a foundation for more extensive research.

High-isolation Wi-Fi Antenna System based on Metamaterial

The Applied Computational Electromagnetics Society Journal (ACES) (2023)

Zhihao Chen Ziqin Wang Fangyuan Chen Xi Hou Yong-Hong Zhou

In this research, an inverted L shaped Wi-Fi antenna with a metamaterial (MTM) decoupling unit is proposed. This swirly-shaped antenna has a compact geometry size of 0.1 wavelength. The metamaterial decoupling unit is placed between the antenna elements to improve the isolation to reduce the mutual coupling. The antenna’s isolation reached 20.7 dB from 2.4 GHz to 2.48 GHz, and 23.5 dB from 5.15 GHz to 5.85 GHz, after the metamaterial unit was introduced. This designed methodology reinforced the anti-interference capability. This compact and low-cost antenna is especially suitable for application in high-density Wi-Fi 6 systems.
