This paper reports recent theoretical modeling and analysis of traceable peak envelope power measurements for mobile communications. Double Sideband Large Carrier (DSB-LC) amplitude modulation has been used, for establishing the measurement traceability to primary RF and microwave power standard. In this work, the reference peak envelope power calculated from modulation index and reference average power is used in calibrations. This is followed by performance comparison of the proposed model with detailed uncertainty analysis.

Electrothermal characteristics of PIN diode under the injection of two types of high power electromagnetic pulse signals are numerically simulated by a self-developed semiconductor device simulation GSRES. The curves of burn out time and amplitude of injection electromagnetic pulse (EMP) and high power microwave (HPM) signals are calculated. Response of carriers in diode is numerical simulated. As simulation results show, under the injections of EMP signals, the charge is concentrated in the PN junction, and the peak value of electric field and the hot-dot of device is in the same position; While under the injections of HPM signals, the charge is concentrated in middle part of device, and the peak value of electric field and the hot-dot of device is in the same position. Temperature in the diode rises slower when the frequency of the HPM signals are increasing. These results can be used in radiation hardening for PIN diode limiter.

A transparent broadband absorber consisting of two periodic graphene resistive patterns separated by dielectric layers is investigated in the paper. The proposed absorber achieves 95% absorption from 39.2 GHz to 200 GHz with 134% fractional bandwidth, due to the multiple resonances provided by periodic patterns and tunability of graphene surface conductivity. Furthermore, the absorber shows relatively stable performance with respect to the incident angle of plane waves and the material of dielectric slabs.

In order to improve the power transfer efficiency and ensure the space cleanliness of power transfer direction in inductive coupled wireless power transfer (WPT) system, this paper proposed a U-WPT system structure. Based on mutual inductance coupling theory, this paper derived the analytic function of power transfer efficiency. By contrasting U-WPT system and traditional two coils system, we drew the condition of improving the power transfer efficiency. With special examples of U-WPT system, we discussed the impact of turns and location of intermediate resonant coil to the power transfer efficiency. The experimental result shows: subject to the condition of power transfer efficiency improvement, by designing reasonable intermediate coils, the power transfer efficiency can be increased from 8.27% to 74.83%, and the power transfer direction's space is cleaner. The result shows that U-WPT system can effectively improve the power transfer efficiency in ensuring the cleanliness of the space situation.

In real environment wearable devices are used, ESD occurrence conditions are considered to be different from previous test methods because wearable devices are usually held by users in their body. In our previous study, we measured electrical stress induced by ESD from a charged human's fingertip to grounded objects on wearable devices held in charged human. From these results, shapes of the induced voltage waveforms, their durations, and amplitudes are quite different in wearable device's circuit structure. Especially, durations of the induced voltage waveforms at high impedance line are very long around ten or hundred microsecond order. The shape of these induced voltage waveforms have single peak and exponential decay curve after 1st peak. As this long duration has possibility to keep circuit high-level long time, it is considered to be one cause for malfunctions. Therefore, in this study, we considered characteristics and generation mechanism of the long duration induced voltage by additional experiments.

This paper proposes a method that can generate striplines (SL) crosstalk with opposite polarity against microstrip lines (MS) crosstalk by designating specific dielectric constant difference between core and prepreg of striplines. And it also demonstrates how the crosstalk cancellation can be achieved by superposition of crosstalk caused by microstrip lines and the designed striplines.

There are three kinds of typical electromagnetic calculation methods, i.e., high frequency asymptotic method, differential equation method and the integral equation method, which are represented by physical optics (PO) method, finite element method (FEM) and moment method (MoM), respectively. Feature selective validation method was proposed by IEEE EMC Association 1597.2 standard in 2011. In this paper, feature selective validation method is used according to the aforementioned three methods to calculate the radar cross section (RCS) of the reduced size Brahmos missile model in two different frequencies. The differences of the results are analyzed. Results show that the similarity between the results of using PO method and MoM is poor, especially in the lower frequency. However, the results of using FEM and MoM are quite similar. Besides, the similarity does not change with the frequency.

Power system harmonic distortion is mainly caused by non-linear loads and power electronics used in the electrical power system and distributed renewable energy systems and Microgrids. The presence of non-linear loads and the increasing number of distributed renewable energy systems in electrical grids contribute to changing the characteristics of voltage and current waveforms in power systems. Such electrical loads which introduce non-sinusoidal current consumption patterns (current harmonics) can be found in power electronics. In addition, the harmonics can be generated in high voltage (HV) DC power systems, distributed renewable energy systems and Microgrids, and in HV power system caused by Geomagnetic Disturbances (GMDs) and Geomagnetic Induced Currents (GICs). This paper introduces and develops harmonic balance finite element method (HBFEM) and its application in power system and distributed renewable energy systems and Microgrids.
