Jafari, Seyedfaraz. « Near-field millimeter-wave radio-frequency exposure analysis ». Electronic Thesis or Diss., Institut polytechnique de Paris, 2023. http://www.theses.fr/2023IPPAT034.
Texte intégralThis thesis aims to determine the absorbed power density (APD) considering the coupling and multiple reflections between the antenna and the human body, which poses challenges in assessing APD due to their close proximity.The first part of the thesis explores the concept of measuring APD inside a skin tissue phantom, specifically focusing on its application in 5G technologies.However, measuring APD inside the skin tissue phantom is limited due to the shallow penetration depth of fields at millimeter and quasi-millimeter waves. To overcome this limitation, a reconstruction technique is employed, utilizing the backward plane-wave spectrum(PWS) method. The electric field is sampled at a specific distance within the phantom, enabling the determination of APD at the human skin surface.In the second part, a non-invasive approach based on the dyadic Green's function (DGF) is proposed for APD assessment. This method takes into account the coupling between the human skin model and the device under test (DUT). The entire space is dividedinto two half-spaces : the upper half-space (z > 0) is filled with air, where the antenna is positioned, and the lower half-space is filled with an equivalent human skin liquid or solid. The electric field integral equation (EFIE), based on spatial DGFs, is solved using the method of moments (MoM) to reconstruct the equivalent currents. The electric field is sampled on the surface of a hemisphere surrounding the antenna, and the APD is evaluated based on the reconstructed equivalent currents beneath the air-phantom interface.In addition to the proposed techniques, the thesis investigates the measurement requirements for both approaches, including E-field measurement uncertainty, sampling angular resolution, and the required size of the phantom.The findings demonstrate that the proposed techniques present a novel methodology for assessing APD, taking into consideration the coupling between the human body and the antenna, particularly in the context of exposure to handheld devices operating above 6GHz

Texte intégral« e. The transfer basket containing the items to be cleaned was lowered into the immersion sump , and statically (i.e. no liquid flow) sonicated for a finite pe-riod of time, usually 15 minutes. f. After static sonication, the rinse pump was turned on and the liquid in the immersion bath was circulated through the activated carbon columns at a rate of1,700 ml/minute for a finite period of time. The circulation time ranged fro m 15 minutes to 2 hours, depending on the purpose of the test. g. The rate of decontamination was monitored by following the concentration of the contaminant in the decontamination liquid (HFE-7100). h . Steps e and f were repeated until the presence of contaminant in the circulat-ing liquid could no longer be detected. i. When the immersion sump liquid was free of contaminant, the transfer basket was moved from the immersion sump to the superheat sump and dried for 30 minutes to remove liquid drag out. j . The transfer basket was removed from the Poly-Kleen™ system. The test pieces were removed from the basket, visually examined, photographed under visible and UV light, reweighed, and archived. I n order to maximize ultrasonic power density, the minimum amount of liquid needed to cover the parts being cleaned was used. Typically, the sump contained from 130 to 180 mm (5 to 7 inches) of liquid, which corresponds to a liquid vol-ume of approximately 15 liters to 30 liters (4 to 8 gallons) and a corresponding ul-trasonic power density of 26 to 18 watts/liter (100 to 70 watts/gallon). In prelimi-nary tests, it was noted that immersing and sonicating the test samples when the immersion sump was filled to the brim (about 53 liters (14 gallons)) did not result in effective cleaning. At that volume, the ultrasonic power density had dropped to a value of 8 watts/liter (30 watts/gallon). While this value would be considered marginal in a stainless steel ultrasonic bath, where the ultrasonic waves can be re-flected from the walls back into the liquid, in a polypropylene bath in which the walls absorb rather than reflect the ultrasonic waves, this power density level is too low. If parts were also contaminated with biological agents, after Step h, they would be sonicated in a fluorinated surfactant/HFE-7100 solution that would be circu-lated through microfilters to remove suspended materials. The parts would then be rinsed in fresh HFE-7100 to remove fluorocarbon surfactant residues, and then dried as described above. Table 3 lists the sensitive equipment decontamination experiments that were carried out in the Poly-Kleen™ system during the course of the program. The combination of equipment processed, contaminants used, and monitoring method(s) examined are listed in this table. The results of the various cleaning re-sults are summarized in Table 4. This table records the weights of the items listed in Table 3, before and after contamination, as well as the post-cleáning weight and visual appearance of these items. » Dans Surface Contamination and Cleaning, 129–36.
