TEM waveguides are widely used for radiated emission and immunity testing of small EUTs. Several standards use product specific test setups with TEM waveguides. To support these TEM waveguide applications, IEC has now published the international basic standard IEC 61000-4-20 on EMC testing and measurement techniques using TEM waveguides. This article summarizes the standard, describes the validation procedure of a GTEM cell and the emission testing of a small EUT

A method to measure the S-parameters of a transformer-type balun is investigated. The two baluns to be measured are regarded as error equivalent circuits in the TRL calibration of a network analyzer. The required conditions for this method are shown, and the errors due to the conditions are estimated. The complex antenna factor (CAF) of a dipole antenna with the balun is determined form the S-parameters measured by the TRL method, and compared with the result obtained by the three-antenna method

Distribution of the currents on septum inside the GTEM-cell directly influences the distribution of electric and magnetic field. The resistors, which are placed on the septum, are used for matching the characteristic impedance of the structure (50 Omega). Their influence is important for frequencies below 100 MHz. Computer modeling of the current flow prior to the building of the GTEM-cell is necessary. The modeling was done using a computer program "Microwave office 2000". The position of the resistors on the edges of the septum was shown to give better VSWR than if they are placed in the center of the septum

The experience described in this paper is valuable for both microcontroller/ASIC manufacturers and their customers. Based on the international standard IEC 61967 for electromagnetic emission characterization of clocked semiconductor devices, the most important test setups are described. The common usage of those test standards by semiconductor manufacturers enable the comparison of several design steps. On the other hand, system designers are able to compare several competitive microcontrollers/ASICs with respect to their electromagnetic emission behaviour

In this paper authors have made analysis of factors that affect on magneto static wave oscillator's (MSWO) frequency. Authors have offered a method of temperature stabilization of MSWO frequency based on magnetization of ferrite film under certain angle to perpendicular that is easy to realize. This method allow to compensate temperature changes of ferrite saturation magnetization as well as temperature coefficients of magnetic system field either positive and negative signs. The influence of ferrite parameters, frequency and MSW length on value of temperature stable magnetization angle has been investigated. Demands for frequency determinating element (FDE) have been considered and shown that FDE with high quality parameter R and big phase increment over pass band (over 2pi) is needed for designing MSWO with low noise level and wide band tuning

A novel FDTD technique to model dispersive chiral media with Lorentzian electric and magnetic properties is demonstrated. This technique is based on the implementation of wavefield decomposition along with the piece-wise linear recursive formulation. Propagation of electromagnetic fields through a chiral slab will be calculated with the new formulations and validated through comparisons with known analytical solutions. The methodology introduced and discussed within this paper will provide the foundation to develop useful design tools for numerous EMC applications, including effective shielding mechanisms and improved antenna designs. This formulation is the first of its kind in the FDTD community

Due to recent deregulations in the EU utility market, it appears to be tempting to compete with classical telecom providers now also over utility owned power lines in the LV mains grid e.g. for broadband Internet access in mostly residential areas. PLC (power line communications, sometimes called PL-T standing for telecommunications) uses unshielded, 230 V/50 Hz low voltage distribution cables inside and outside of buildings as transmission medium up to Mbit/s data rates. This requires mains injected radio frequency levels (e.g. total power < 1W, spectral power e.g. -40dBm/Hz, 1-30 MHz) that are EMC critical, with common mode currents on wirers e.g. 20dBuA at 1MHz. Such signals are normally injected at the distribution transformer. Aside from the growing international standards making effort, there are today(11/02) applicable German regulations in place (RegTP, NB 30-07/01). controlling radiated emissions below 30 MHz, in the short wave user spectrum. Most standards give field strength limitations only above 30MHz. In contrast to PLC, other competing broadband services like x-DSL and cable TV use well engineered, symmetrical telecom line with less disturbance potential. Regulations and standards are supposed to protect, among others, sensitive monitoring/communication services in both military and government. The latest PLC developments with all pro and cons are analyzed, computer simulations discussed and compared to many collected EMC critical (e.g. 20-40 dB over NB30 limits) measurement results. From now EU-wide available, real wide-spread PLC systems in field trials, first conclusions can be drawn. Some aspects of the EU mandate M313 regarding telecom networks will also be discussed. A review of the current state of PLC and related wire broadband technologies, with the focus on Europe, will be presented. Included are sky wave propagation issues, man made noise floor and also VHF-leakage of CTV-systems into air traffic control frequencies in Germany
由于欧盟公用事业市场最近放松了管制，现在似乎很容易与传统电信提供商竞争低压主电网中公用事业拥有的电力线，例如用于大多数住宅区的宽带互联网接入。PLC(电力线通信，有时称为PL-T代表电信)使用建筑物内外的无屏蔽，230 V/50 Hz低压配电电缆作为传输介质，数据速率高达Mbit/s。这需要电源注入的射频电平(例如总功率< 1W，频谱功率例如-40dBm/Hz, 1- 30mhz)是EMC关键，在电线上的共模电流例如在1MHz时20dBuA。这些信号通常注入配电变压器。除了不断增长的国际标准制定工作外，今天(11/02)有适用的德国法规(RegTP, NB 30-07/01)。在短波用户频谱中控制低于30mhz的辐射发射。大多数标准只给出30MHz以上的场强限制。与PLC相比，其他与之竞争的宽带服务，如x-DSL和有线电视，使用精心设计的对称电信线路，干扰潜力较小。法规和标准应该保护军队和政府敏感的监控/通信服务。分析了具有所有优点和缺点的最新PLC发展，讨论了计算机模拟，并与许多收集的EMC关键(例如20-40 dB超过NB30限制)测量结果进行了比较。从目前欧盟范围内可用、真正广泛推广的PLC系统的现场试验来看，可以得出第一个结论。还将讨论欧盟关于电信网络的M313指令的某些方面。将介绍PLC和相关有线宽带技术的现状，重点是欧洲。其中包括天波传播问题，人为噪声底，以及德国ctv系统的甚高频泄漏到空中交通管制频率

The classic fall-of-potential method (potential electrode is between grounding grid and current electrode) is universally used for measurement of grounding grid impedance for many decades. The inductive coupling between the current electrode and potential electrode leads is analyzed for different homogeneous earths, operating frequency and separation between leads. Also, in urbanized area very often the potential probe can not be located at the proper position, because of the presence of buildings, paved lots, underground metallic pipes, etc. In those cases the direction of the potential probe needs to be placed under angle a = 90deg-270deg towards the direction of grounding grid-current electrode, method known as alternative fall-of-potential method. The purpose of this paper is to calculate errors of grounding resistance for different types of grids buried in two-layer earth models, when the potential probe is under some angle to the straight line grounding grid-current electrode. The obtained results of the errors can be shown as family of curves, which can be used in practice for correction of measured grounding grids resistance values
