“…GTEM cells can be used to perform tests over a certain EUT in order to evaluate its immunity to an incidental electromagnetic field [36]. The analysis of the QP values reveals that none of them exceeds the maximum allowed limit of 40 dB(µV/m) for the range (30-230) MHz and 47 dB(µV/m) for the range (230-1000) MHz [29].…”

In this article, issues related to electromagnetic compatibility and energy/power quality for a laptop are addressed. Power quality problems are outlined. Testing frameworks (developed by authors) are presented and discussed for a laptop when two different sampling frequencies are used: 80 kHz and 19.2 kHz. Waveforms corresponding to the voltage across the laptop’s terminals and current absorbed by it were acquired. Recordings and numerical processing, based on original software using Fast Fourier Transform, are discussed, and the analysis of waveforms in both cases is performed. Various power quality indices were calculated. Theoretical and practical aspects related to the determination of power quantities, power flows, and power factor are presented. Some conclusions concerning different ranges of frequencies are presented, along with some considerations for power quality problems. Tests for conducted emissions (single phase and neutral wire respectively) and for the radiated emissions (for horizontal and vertical polarizations) are presented. Comparisons to the emission standards were made. The immunity behavior for a laptop is discussed according to immunity standards. It is shown that new measures (e.g., active filters) are necessary for network protection when connecting a laptop to the network. Some considerations, based on the authors’ observations concerning new standards for power quality and electromagnetic compatibility, are outlined.

“…A complementary immunity experiment is performed with Transverse Electrical-Magnetic mode cell (Crawford TEM cell) configurations, including the thermal experiment solutions. TEM cell is commonly used for EMC characterization, from 1MHz up to 3GHz, at PCB and Integrated Circuits levels [8] [9]. As a well-suited alternative to large size experimental equipment for conventional radiated far field characterization, it allows very pertinent solutions for selective electromagnetic characterization of single electronic devices enclosed in the shielded cell environment.…”

“…We actually investigate these effects mainly for one of the most thermal sensitive chips used in power electronic modules, including driver technology [4] [5]. Actual state-of-the art of radiated EMC characterizations, both emission and immunity, can be performed over Printed Circuit Board(PCB) and Integrated Circuits(IC) with Near-Field probe's sets guided by a motorized scan table and/or Transverse Electro-Magnetic(TEM) cells [6] [7] [8]. In these two cases, often dedicated PCB's are especially designed, inherently for TEM cell, to comply with Standardized Cell Aperture (10cm*10cm), and also to separate inside/outer electromagnetic sources and victims [9].…”

“…The systems in [7] and [11] provide a more detailed design approach, but do not highlight simulation or practical manufacturing difficulties in building GTEM cells in-house. The current body of literature's upper limit of consideration on field strength in GTEM cells is 200 V/m [12] at frequencies well below 1 GHz.…”

Abstract-Gigahertz transverse electromagnetic (GTEM) cells are used extensively in industry for testing the impact of defined E-fields on devices sensitive to electromagnetic interference. Compared to anechoic chambers, GTEM cells are small, inexpensive and require less powerful amplifiers to achieve the same field strength. This paper presents the design, simulation and qualification of a compact GTEM cell capable of generating field strengths in excess of 600 V/m over a 20 × 20 × 15 cm test cavity, whilst being less than 2.2 × 1.3 × 1 m in total size. Specific hybrid FEM-MLFMM simulation strategies are provided to examine high power device characteristics prior to manufacturing, including accurate modelling of absorber materials. Practical notes on manufacturing and qualification are also presented.
