Special Issue Information
Dear Colleagues,
- Accurate interference field strength measurements require high-sensitivity magnetic and electric field probes. The miniaturization and integration of EMC probes is a technically demanding procedure.
- Modern sensors, regardless of their intended purpose, require compact integration which causes EMC issues. Optimized/enhanced EBG-patterned ground planes can be used as such sensors for high-frequency EMI suppression.
- Novel high-speed microprocessor unit sensors emit/receive in adjacent structures. The implementation of shielding enclosures based on flexible and lightweight metasurfaces for EMI blocking is a challenging task.
- Inductance-to-digital converters (LDCs) are very important in modern sensor technologies. LDC devices drive an inductive sensor that intentionally radiates a magnetic field to sense nearby conductive objects based on the induced eddy-current in it. As this is a narrow-band resonance-based sensing technique, radiated emission problems are inevitable. Therefore, apart from its application in NDT devices, it also raises all the relevant issues concerning EMC, such as shielding, trace and coil shielding, ground planes for radiated emissions suppression, rise- and fall-time considerations, supply/return routing, etc.
-State-of-the-art metamaterial-based sensors use artificially designed subwavelength structures which can effectively modulate electromagnetic fields for sensing applications. Surface-enhanced spectroscopy technology based on metamaterials exploits various resonance mechanisms (localized surface plasmon resonance, Mie resonance, bound states in the continuum, Fano resonance), enabling the implementation of high-sensitivity sensors in NDT, especially for distinguishing between different samples. However, major challenges regarding performance, reliability, integration, and sensitivity still need to be addressed.
