Shortcomings of the standard ways for tests of electronic devices for immunity to ultrashort electromagnetic pulses (US EMPs) are considered. The method of a choice of simulators being based on use of key parameters of the pulse electric disturbances induced in critical circuits of equipment is offered. This method allows choosing the simulator or some simulators providing the most severe conditions of tests.

Singapore is rapidly expanding its Rapid Transit System (RTS) network to cater for increasing public transportation demand. Hence, new RTS extensions are being built at a faster pace. With the current systems in the vicinity and the increase in the complexity and interdependency of various RTS systems, effective Electromagnetic Compatibility (EMC) practice is an important integral part of project management to reduce the possibility of electromagnetic interference (EMI) and achieve successful overall system wide compatibility. This paper highlights the challenges faced by Land Transport Authority (LTA) in EMC Management during the Tuas West Extension (TWE) project. In light of these challenges, LTA has developed new strategies and methodologies suitable for future RTS projects implementation.

This paper systematically discusses fabrication process, morphological observation and electromagnetic noise suppression performance of new series of the non-woven fabric type noise suppressor consisting only of the meltblown thin fibers. Effect of contact resistance has been clarified experimentally for the first time as the sheet resistance becomes the less and accordingly the loss ration becomes higher as the pressure during fabrication increases, and as the heat treatment is applied to weld the fibers. The noise suppression performance was as high as conventional thick-thin fiber type NSS.

Dual Norton model is a two-port model based on the method of characteristics and finite differences that often does not require segmenting the transmission line. This method makes the calculation of aerial lines be simple. However, it is evident that the accuracy of this model should be affected by Earth resistivity, frequency and line length, which has not discussed in detail. In this paper, an error evaluation method is proposed and the application scope is investigated for the dual Norton model.

In this paper, an improved model of the vertical risers of a transmission line is proposed and validated. The proposed improved model, which can be readily implemented in the frame of a classical transmission line formulation, provides accurate results at frequencies much higher than the upper frequency limit of the classical transmission line theory. For example, for the assessed line (with a height above the ground of 10 cm), the improved model is still fairly accurate at around 1 GHz, whereas the classical model starts to deviate from the accurate solution at around 150 MHz.

An accurate model is developed to predict the shielding effectiveness of enclosures with aperture arrays. The impedance of the aperture array is expressed as a function of the spacing between apertures, the diameter of apertures, the incident angle, and the thickness of the perforated plate. The model outperforms the traditional models in that it can consider the thickness of the perforated plate, the spacing between apertures, the mutual coupling between apertures, the incident angle, and the polarization angle at the same time.

With the quick development and widespread use of mobile phones has led to arising concern about the possible adverse health effects of radio frequency electromagnetic field exposure. This study aims to present the dosimetry analysis of the electromagnetic fields induced by mobile phone on human endocrine glands. A finite-difference time-domain (FDTD) method was employed to calculate the specific absorption rate (SAR) in a realistic human head-neck model from exposure to a generic handset at 1750 MHz. The results show that the locally induced SAR in thyroid gland is much larger than that in both hypophysis and hypothalamus glands. The induced SAR in thyroid for the mobile in short message service (SMS) position is much larger than that in the voice position. However, in all of the examined cases, the SAR values in endocrine glands are all below the IEEE safety standard.

The problem of bi-objective radar waveform design for target estimation and electromagnetic compatibility is addressed in this paper. To improve the estimation performance, the mutual information (MI) between the received signal and the target impulse response is used as the objective function. While for electromagnetic compatibility, the spectral power of the transmitted waveform should be suppressed in some certain frequency bands. The optimal radar waveform is designed for both the aforementioned two objective functions under the energy and modulus constraints. An iterative algorithm is proposed to solve the bi-objective optimization problem. Optimal waveform is obtained for different weights of the two objective functions. The performance of the waveform is evaluated in terms of MI and spectral power allocation in the frequency bands.

The performance of the wireless power transfer (WPT) system is highly constrained by the coils in the coupling field. The coils can be fabricated as multi-layer Printed Spiral Coil (PSC) due to the development of the Printed Circuit Board (PCB) technique. This spatial effective coil implements the miniaturization for medical implants with higher inductance and lower resonance frequency. The accurate design of the PSC will be extremely complex with the analytical derivation based on Maxwell's equations. In this work, we proposed a new formula to connect the geometrical parameters with the self-resonance frequency and the Q-factor of the PSC. The numerical and experimental method are used to analysis the factors in our formula. We find that the resonance frequency is very sensitive to the number of turns and layers in the PSC. This mathematical method provides a more accurate approach for the coil design and optimization.
