Abstract: In an electromagnetic field measurement system, a probe substrate and a transmission line substrate form a T-shaped structure, where the probe substrate forms a cap and the transmission line substrate forms a stem of the T-shaped structure. The probe substrate includes a probe having a first probe element, a second probe element, and a reference plane. The first probe element and the second probe element are disposed so that there is an axis of symmetry between these probe elements, whereby the axis of symmetry is perpendicular to the transmission line substrate. The transmission line substrate includes a transmission line structure coupled to the probe. The transmission line structure separately guides the first probe signal and the second probe towards a measurement processing arrangement that can provide a measurement results on the basis of the first probe signal and the second probe signal.
Abstract: An oil-in-water emulsion includes an aqueous phase and an oily phase, the aqueous phase including water and a relaxing agent, and the oily phase including an oil and at least one surfactant. The emulsion has dielectric properties simulating dielectric properties of the human body. A device including the emulsion, a simulated human body part filled with the emulsion; and at least one system capable of measuring a local specific absorption rate when the simulated human body part is exposed to an electromagnetic field are also described. A method for conducting specific absorption rate tests of an apparatus radiating an electromagnetic field including using the emulsion, and a process for manufacturing the emulsion are also described.
Abstract: (EN) A system (MSY) for measuring an electromagnetic field comprises an antenna device disposed on a plane (AB1). The antenna device is arranged to provide a pa it of signals representative of a pair of orthogonal components of the electromagnetic field. A printed circuit (PT1) for signal transmission is orthogonally disposed with respect to the plane (AB1) on which the antenna device is disposed. The printed circuit (PT1) comprises a transmission line coupled to the antenna device to transmit the pair of signals provided by the antenna device towards a measurement module.
