This paper discusses computational electromagnetics (CEM) modelling used to investigate various TEM cell configurations in order to optimize the method for testing a military aircraft. A baseline for the study was achieved by comparing a simulated aircraft in the DSTO TEM cell, on an open area test site (OATS) and in free space. The model was then used to investigate improvements to the TEM cell performance by modifying its design. It is shown that by changing from a solid to wire septum, gains are achieved in the low frequency performance of the cell. We also report on studies of active TE mode resonance cancellation. All results are discussed with respect to implications for future TEM cell designs","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.

However, the transmission characteristics of an indoor AC mains line have not been clarified. We studied the influence of the appliance operation state on the transmission characteristics of the indoor AC mains line. The AC mains line and appliances were represented by four-port networks and two-port networks. The transmission characteristics were calculated by a model constructed with these networks. The two-port network parameters of the appliances were measured in both operating and stop states. The equivalent circuits were determined for both states based on the condition that the frequency characteristics of the circuits agreed with the measured value. A simple AC mains system was constructed and the transmission characteristics were measured to compare with the calculated value in various states. The results indicate that the calculated value agreed well with the measured one, and the transmission loss deviation resulting from the appliance state was within 10 dB. A common mode choke coil was inserted between the AC mains line and the appliances to reduce the transmission loss deviation resulting from different states. The measured and calculated values indicate that the deviation was reduced from 10 dB to 0.5 dB by inserting the filter.","PeriodicalId":6459,"journal":{"name":"2005 International Symposium on Electromagnetic Compatibility, 2005.

The project's product is defined as an operational prototype. On one hand, this prototype proves the system's functional properties as were specified by the customer, while on the other hand serving as a first article that is required to withstand all of the environmental conditions as a serially-produced system, including full EMC requirements. The unique system which is being addressed here has multiple, diverse capabilities and is comprised of elements and units belonging to various families, e.g., electronic boxes, electro-optical units, inertial sensors, functional display, computer, etc. The units are based on home-developed and commercial off-the-shelf (COTS) units (military as well as civilian/industrial).

Key to predicting their near field emissions is the calculation of common mode current on the antenna which is difficult at low frequencies.

Furthermore, lumped parameter RLC equivalent circuits are developed from quasi-static means and correlated to conventional antenna theory.

ISO 7637-2 presents a number of test pulses that are presumed to simulate the actual transients produced in the vehicle. This paper compares three of those pulses (pulses 1, 3a and 3b) to actual transient events which are the result of contact arcing during deactivation of an inductive load. The paper demonstrates that the pulses 1, 3a, and 3b are overly simplistic representations of a more complex waveform.
