A compact and high performance ultra-wideband (UWB) band-pass filter (BPF) based on two strength coupling quarter-wavelength coupled-lines, which were often served as feedlines between the port and resonator, has been designed and fabricated. Firstly, the desired high coupling factor is achieved by using three-line coupled structure and ground plane aperture technology. Then, the two transmission zeros are generated at the two sides of the wideband to improve the selectivity of this filter by the loading stepped-impedance resonator stubs(SIRs). Finally, the proposed filter is validated through both simulated and measured results and good agreement is obtained.

Common method for balise uplink signal demodulation are coherent demodulation, non-coherent demodulation and zero-crossing detection. Based on the characteristics of balise uplink signal modulation method, this paper adopts the time-frequency analysis method of Adaptive Optimal Kernel (AOK) to demodulate the original balise uplink signal received by on-board equipment. According to the European FFFIS (Form Fit Function Specification) coding/decoding strategy to decode the demodulated signal, the demodulation performance of the demodulation method is analyzed by the accuracy of the decoding results of a large number of demodulated data. The results showed that the time — frequency analysis method of AOK can accurately demodulate the uplink signal in the transmission process, its bit error rate is almost zero and has a good demodulation effect.

The precise modeling of permeability is the key to 3-D simulation of current injection probe. In this paper, using the short-circuit coaxial cavity to measure magnetic permeability, two equivalent models is carried out, that one of them is single-turn coil model, the magnetic permeability is calculated by integrating inductance, the other is transmission line-lumped parameter mixed model, the permeability is calculated according to the characteristics of transmission line. First-order Debye model can fit the complex permeability spectrum of ferrite, so this paper sets Debye model reasonably in corresponding parameters by comparison of the calculated magnetic spectrum. Core permeability and coil loops are two of the most important factors that affect the performance of current injection probe. After establishing a precise model, this paper focuses on researching the characteristics of these two factors on probe, which provides theoretical support for producing probes with smooth flatness and small insertion loss in wideband.

As one of the main EMI sources, the traction inverter of EMUs or electric locomotive produces large amount of harmonics and chopper switching noise when it works. It may cause hazard effects or electromagnetic interference to traction motor, track circuit system and ATP system, which may seriously affect the safety of train running. A traction inverter model is proposed in this paper to simulate and study the electromagnetic disturbance that generated by the inverter. Based on the simulation, the common mode noise current of the inverter's output and the radiation level are evaluated. Simulated radiated disturbance result shows good appliance to the experimental tests of a realistic inverter which connected to a motor. The approach explains the disturbance characteristics of inverter and the mode of its emissions.

This paper presents a chipless RFID system based on polarization characteristics. The system consists of a polarization-recognition reader and a variety of tag antennas with specific polarization. The orthogonal dual-polarization antenna of the reader can form arbitrary polarization wave fed by dual-channelamplitude and phase controllable source. The tag antenna with a particular polarization in irradiated area reflects some wave, and the echo depends on the polarization of the tag antenna. Thus, the reader can determine the polarization mode of the tag antenna according to the echo signal. This method has the advantages of large coding capacity, simple signal processing and low cost. Analysis and measured results show that the chipless RFID system can determine the polarization mode of the tag antenna according to two echo signals.

In this paper, the transmission coefficients of high power microwave (HPM) in plasma-filled metallic parallel-plate waveguide is studied by FDTD method. The important parameters of the plasma generated in the waveguide, such as the electron density, are calculated by COMSOL using fluid approximation method. Under the incident wave working in TM mode, the behavior of the plasma is similar to that of the high-pass filtering with 60 dB loss at the cut off frequency.

The next generation of train-control safety computer is designed as double-redundant systems as safety-critical system. Due to the complexity of the safety computer logic, the active-standby switching between the two subsystems involves multiple state transition under several different conditions. The correctness of the switching process needs to be confirmed by formal verification. In this paper, the UML is used to establish the model and the NuSMV is used to formalize the model. An analysis of multiple-faults situation and the dual-hoststate is carried out. According to the result of model checking, an improvement was proposed to optimize the switching process.

An approach to the design of a three-beam linearly-polarized microstrip antenna arrays has been proposed. The presented antenna arrays feature one broadside beam and two symmetrically scanned beams with respect to boresight direction generated with the use of a 3 × 3 Butler matrix as a feeding network. Such a Butler matrix allows to obtain equal power split and 0° −120°, and +120° differential phases at its outputs. The proposed concept has been experimentally verified by development and measurements of a three-element linear antenna array with uniform amplitude taper as well as a five-element linear antenna array with reduced sidelobe level, both operating at 2.5 GHz.
