MAGPy V1.0 for In Situ Evaluations

MAGPy V1.0 is composed of the MAGPy-8H3D+E3D probe and the MAGPy Data Acquisition System (MAGPy-DAS), connected to the tablet PC with the intuitive browser-based GUI. The induced E-field/current density and SAR are assessed by using the coupling transformation function.

MAGPy V1.0 is optimized for in situ exposure and compliance evaluations at any location with high fields, including:

• Automotive/vehicular/train WPT
• Industrial and utility (e.g., industrial welding, induction cooking, electronic article surveillance, and WPT)
• Energy supply (e.g., installation and operators of WPT networks)
• Ubiquitous devices equipped with WPT technologies (e.g., mobile phones, implantable medical devices, wearable devices, and Internet of Things (IoT))
• High power electromagnetic (EM) sources
