“…In this scope, international standards have been established in order to ensure the performance, reliability and the electrical safety of certain embedded electronic systems, for example, to avoid the influence of the radio wave interference [4][5][6]. To study and estimate this EM interference (EMI), numerous studies have been conducted on this topic, in particular, for the modeling and the treatment of the magnetic or H-field radiated both in near-and far-field domains [7][8][9][10][11][12][13][14]. Nonetheless in practice, the magnetic field measurement is generally easier and more precise to carry out because of the facility of the loop probe design and modeling.…”

“…To cope with this computation default, more accurate mesh sizes should be considered.As conclusion, all these Matlab results allow to confirm the relevance of the proposed E-field extraction technique. As developed in[8], any EM field radiation scanned in 2D map can be equivalent to the radiation of the association of either electric or magnetic dipoles. To get more insight about the feasibility of this concept, further investigation was also made in the next section with the measured EM field radiated by an open-end microstrip TL.…”

This paper deals with a technique for calculating the 3D E-field components knowing only the two components (H x and H y) of the H-field in near-zone. The originality of the under study technique lies on the possibility to take into account the evanescent wave influences. The presented E-field extraction process is based on the exploitation of the Maxwell-Ampere relation combined with the plane wave spectrum (PWS) method. The efficiency of the proposed technique is evidenced by comparing the E-field deduced from H-field and the own E-field radiated by the association of electrical-and also magnetic-elementary dipoles in different configurations by using Matlab text programming environment. In addition, as a concrete demonstrator, the concept was also validated with the computation of EM-wave radiated by an open-end microstrip transmission line. As result of comparison, very good agreement between the exact E-field and that one extracted from the H-field was realized by considering the near-field scanned at the height, z = 5 mm and 8 mm above the under test structure at the operating frequency, f = 1 GHz. The presented technique can simplify the difficulties about the E-near-field measurement in EMC applications.

“…Therefore, a tiny MO probe would be a powerful tool in cases where EO probe sensitivity is not sufficient to evaluate signal/power integrity in microscopic regions. Indeed, an ordinary fiber-optic MO probe was successfully used to evaluate the conduction noise characteristics of an LSI by measuring the magnetic near-field over the LSI package pins [17].…”

The basic performance of a newly developed microscopic magneto-optic probe is described. The probe was fabricated by directly depositing a Bi-substituted yttrium iron garnet [Bi-YIG] film onto the optical fiber edge using aerosol deposition. This fabrication process is inexpensive and simple because there are no complicated procedures such as fine lithography and etching. The film is 125-µm-wide, which is the same as the diameter of a typical single mode fiber, and approximately 10-µm-thick. The 3-dB bandwidth and spatial resolution of the probe were found to be about 3 GHz and in the 10-µm order, respectively. Because the developed magneto-optic probe is very tiny and thin, it can be a powerful tool for detailed electrical characterization of densely packaged electronic circuits.

“…Also, spatial undulation of local impedance can be evaluated in conjunction with a complementary EO measurement. Furthermore, it is advantageous in fmding out hidden sources of unnecessary electromagnetic emission [7] High-Spatial Resolution It is attractive to apply the above-mentioned GHzbandwidth MO probe to contemporary RF circuits of fine and complicated pattems. The reduction in its spatial resolution down to the pm range has been thus attempted ,-W -.. [SI.…”
