Polarization, amplitude and phase are three critical characteristics of electromagnetic waves as known. In this article, a general method with high efficiency and low complexity is proposed to realize simultaneously independent control of polarization, amplitude and phase of electromagnetic waves by receiver-transmitter integrated meta-atoms in transmissive geometry. The amplitude modulation is controlled by the rotation angle of top receiver patch, while the phase delay is determined by the rotation angle of bottom transmitter patch without affecting the amplitude. In addition, the polarization is controlled by the polarization of both receiver and transmitter. As a proof of concept, a metasurface with multiple diffraction orders is designed, fabricated and measured in microwave reigonnnogier. The measured results are in excellent agreement with the simulated ones. Our finding offers an alternative way to synthesize arbitrary wavefront shapes of EM waves, and we are looking forward to more highperformance photonic metadevices by applying this approach.

The actual environment of vehicles will inevitably encounter moving obstacles such as pedestrians and vehicles, and the vehicles need to get back to the global path in time after avoiding moving obstacles. In order to avoid obstacles safely, artificial potential field is applied to local dynamic path planning. Aiming at solving the problems of traditional artificial potential field, the traditional artificial potential field is improved in this paper, which include discretizing the boundary of obstacles to ensure the safety of obstacle avoidance, adding random escape force to escape the local minimum and considering the speed and acceleration of obstacles to apply traditional artificial potential field to dynamic path planning. The design of obstacle avoidance for three most common collisions of front collision, rear collision and side collision is carried out. The improved artificial potential field is used to acquire the local path. The simulation results show that the proposed algorithm can obtain local dynamic paths with better safety and real-time performance. Combined with the global path, the path planning of intelligent vehicles is completed in this paper.

In this paper, a sparsely phased array antenna based on six-arm spiral arrangement is proposed for W-band applications. The proposed antenna element consists of a double-layered stacked patch fed by coaxial probe. In order to reduce the element number of the antenna array while maintaining wide scanning angle and low sidelobe, a six-arm array configuration is developed as a substitution of the conventional rectangular array. A prototype of the six-arm spiral array is simulated at 94GHz band. The simulation results exhibit a maximum gain of 28.5dBi with a scanning angle of 30°. By using the six-arm spiral array design, the proposed antenna can achieve 30 degree scanning range with gain loss less than 1.6dB.

A simple system for the measurement of scattering parameters is presented utilizing an open Transverse Electro-Magnetic (TEM) cell. The scattering parameters are simulated in the principle of Finite Differences Time Domain (FDTD). Meanwhile, a classical slot Frequency Selective Surface (FSS) was simulated in the proposed TEM cell, and the results are in greet agreement with the full-wave simulated results in unit cell way.

In this paper, the human arm is selected as the research object to study its path loss for wearable application. Two same all-fabric microstrip antennas with microstrip line feed are designed using conventional fabric materials and conductive fabrics, where the less electromagnetic wave propagate along the arm than that of the dipole antenna etc. The measured S21 parameter of same curvature in free space and on the arm for both are compared and analyzed, and then get the path loss for the arm characteristics. Finally, the curve fitting technique is used to fit these two measured curves according to the fundamental of the path loss. The results show that the path loss index in free space at the resonance frequency of 5.8GHz is 2.23, while it is 1.03 on the arm.

An artistic antenna shaped like Chinese character ‘Shan’ was proposed in this work. ‘Shan’ serve as a radiation patch and the feed point is placed on the right side of the re-radiation patch. The transmission zero of the proposed antenna was at 3.51 GHz and the impedance bandwidth was 25 MHz (3.495 GHz-3.520 GHz). The simulation maximum gain of the antenna was 5.735 dBi. In addition, the proposed antenna could also be redesigned as a dual-band antenna. Thus, the proposed antenna shaped like ‘Shan’ has a promising potential for the application of 5G communication.

The traditional Fourier algorithm cannot fix the problem of non-stationary noise deduction for MEMS-IMU, therefore this article uses Empirical Mode Decomposition (EMD) algorithm to denoise the signal. In this article, Extreme Learning Machine (ELM) is combined to reduce the influence of end effect in the decomposition. First, the MEMS-IMU simulate signal generated by matlab is taken as the test object, and EMD as well as ELM extension decomposition are carried out for it respectively. The decomposition noise reduction effect is compared and analyzed to study the role of EMD and ELM in the process. Second, carry out a test on the authentically measured MEMS-IMU signal. In de-noising the MEMS-IMU simulate signal and authentic signal, we can analyze the noise deduction effect and observe the changes of parameters related to random error. The results show that the method based on ELM and EMD can achieve good noise reduction effect for MEMS signal.

A novel magneto-electric (ME) dipole antenna is presented in this paper, which owns the characteristics of low cross polarization level and high front-to-back ratio (FBR) for the Sth-generation (5G) indoor communications is described. By dividing the conventional patches into two pairs of rectangle patches and four pieces of parasitic patches, the current which produces cross-polarization can be offset. Furthermore, the vertical fence can effectively widen the beamwidth of antenna. Experiment results demonstrate that a broad frequency bandwidth of 3.3-4.2 GHz (24%) can be achieved for 5G communications. Besides, a cross - polarization level below −20 dB and a FBR level of approximately 26 dB in the operating bands. Noting that a wide beamwidth of 100° for E-plane and H-plane is also obtained.
