SPEAG has pioneered the research and development of electromagnetic probes. All probes have been optimized by means of full-wave 3D simulations to achieve maximum spherical isotropy with avoidance of or compensation for any field distortion from mounting materials. Special techniques have been developed to minimize secondary modes of reception. Only the best low-loss materials are used, making the probes very rigid and compatible with almost any media. SPEAG has also pioneered the calibration techniques that enable the most precise measurement of electric, magnetic, dosimetric, and temperature quantities.
