The formulas of tortuous channel lightning electromagnetic field are obtained by decomposing the current micro-source dipole and solving Maxwell's equations. The waveforms of lightning electric and magnetic fields in different areas are calculated using the transmission line model and pulse function. Then, the characteristics of lightning electromagnetic field for different channel geometries and the impact of lower section discharge channel length on electromagnetic field initial peak value are analyzed by comparing the waveforms of lightning electromagnetic fields. The results show that, the difference between the electromagnetic field waveforms of two models will decrease with the increasing of the distance and the upper section of discharge channel has little impact on electromagnetic fields in near area but the electromagnetic fields will be influenced by the upper section of discharge channel in intermediate and far field regions. Moreover, the peak value of tortuous channel lightning electromagnetic field in different field regions is mainly determined by the lower section length of the discharge channel.

Since 1960s, no solutions have been found both home and abroad to the theory and protective technology related to hazard influences of a high voltage transmission system on a communication system. Previously, the major technical measure against comprehensive hazards of the strong current is to make them separated. However, in city planning, it is inevitable to arrange them closely or construct them on the same site. Whether a communication system mainly having the weak current and a high voltage system in hundreds of kilovolts can co-exist and how to make them co-exist have become a worldwide puzzle which influences the development of communications. When the cloud data center of a communication system is constructed with a high voltage substation together, three critical technical problems should be solved: influences of hazards caused by the rise of the earth potential in thousands of kilovolts on the communication system due to the power- frequency short-circuit accident of the strong current system; influences of the electromagnetic field in the high-voltage power distribution room on the communication system; and influences of the on-off of high-voltage strong-current grounding and information grounding on communication equipment. When the high voltage substation works normally, the power frequency magnetic field may cause hazards to the information storage equipment of the cloud data center constructed on the same site. By measurements and analyses, this article systematically summarizes characteristics of the power frequency magnetic field generated by the substation.

In order to study effect on electromagnetic field in cavity affected by penetrating conductor and its circuit, different models of penetrating conductor and its circuit were established. Electromagnetic simulation software CST was used to do simulation. Experimental system was set up with a GTEM chamber, a vector network analyzer, a power amplifier, ETS electric field probe to verify simulation results. Laws of influence on electromagnetic field in cavity by penetrating conductor coupling and its terminal load effect have been revealed. Results show that electromagnetic field in cavity is affected by the combination of penetrating conductor resonance and cavity resonance. Electric field strength got extremum at resonant frequencies. Shielding effectiveness curve of penetrating conductor open at two terminal was close to it of penetrating conductor loading but not grounding model. Electric field of penetrating conductor loading grounding directly was significantly lower while resonant frequency reduced. Changing laws of penetrating conductor loading floating grounding was similar to model of penetrating conductor loading but not grounding in low frequency and similar to model of penetrating conductor loading grounding directly in high frequency.

Summary form only given. The investigation of the interaction of biological tissue, i.e. cells, organs or living being, and electromagnetic waves has been of interest to the scientific community for a very long time, but became a research focus with the introduction of mobile phones in the 1990-ies. The primary natural source of RF fields is the sun. Human-made sources, however, emit the majority of fields in the immediate environment of the community, home or the workplace. Most RF fields found in the environment are due to commercial radio and TV broadcasting and to telecommunications facilities. RF sources in the home include microwave ovens, DECT telephones and Wi-Fi routers. In the workplace, there are a number of industrial processes which use RF fields: dielectric heaters used for wood lamination and the sealing of plastics; industrial induction heaters and microwave ovens. Today the largest source of RF for the general public is the use of mobile telephones. Except when phones are used in a hands-free position or used to send data, mobile telephones are generally held against the head when a call is being made and the antenna receives and sends the signal. The head of the user is in the near field of the source because of the distance of the antenna to the head is typically a few centimetres. Due to this close proximity, the interaction of RF energy has to be considered due to possible destructive effects. This talk will give a comprehensive overview of the different identified interaction mechanisms and explain their physical principles, and will outline ways to approach the understanding of the mechanisms either by numerical simulation or measurement. Additional information will be given on the most important effect: the thermal heating of tissue which is exposed to electromagnetic waves. The fundamental criteria are explained, including a detailed discussion of the Specific Absorption Rate (SAR) and various ways to estimate the SAR values for different tissues. The talk will include a review of the relevant literature, the most cited overview articles and publication database. Concluding, a short statistical investigation will be given on the possible health effects.

A design method for miniaturized planar holographic antenna with surface-wave launcher feed is proposed. The antenna is fed by a printed surface-wave launcher(SWL) instead of a monopole or a horn, which leads to a complete planar antenna structure (operating between 23-26GHz). For the design example radiated at 30° off the normal. Two prototypes of miniaturized planar holographic antennas are designed by simply cutting out the inefficient region. The first demonstrates that the area of the miniaturized is 48% smaller and the gain is 0.7dB in simulation higher than that of the original antenna. Similarly, the second achieves that the area of the miniaturized is 72% smaller and the gain is 0.3dB in simulation higher than that of the original antenna.

Wireless body area networks (BANs) are attracting much attention to healthcare and medical applications. Electrostatic discharge (ESD) may be a major electromagnetic (EM) noise source to interfere the wireless communication performance. In this study, we measured EM noise power at 2.4 GHz and 30 MHz bands for indirect ESD immunity testing according to the IEC 61000-4-2 standard, and derived a statistical ESD noise model based on the measurement results. The ESD noise power was found to follow lognormal distribution.

In this letter, a modified domain decomposition finite-difference time-domain method based on weighted Laguerre polynomials (DD-WLP-FDTD) is proposed for nonuniform subdomain interfaces in TEz case with perfectly matched layer (PML) absorbing boundary condition (ABC). The feasibility and accuracy of this modified DD-WLP-FDTD method are confirmed by two numerical examples. The maximum of the error is less than 0.0008% compared to the results of the conventional WLP-FDTD method and the relative reflection error of the PML ABC is less than -64 dB.
