The article describes a new type of microresonator called a planar inverse anapole microresonator. This device consists of an anapolic substrate with an anapolic conductor on top, which includes two inverse anapole patterns.
Each inverse anapole pattern has a semi-annular arm with two arm tendrils and a medial arm terminating in a medial tip. The two medial tips oppose each other, creating a concentrated magnetic field region between them when the device is exposed to microwave radiation.
The article also discusses a process for performing inductive-detection electron paramagnetic resonance (EPR) spectroscopy using this microresonator. The process involves directing microwave radiation through a conductor and subjecting the inverse anapole patterns to this radiation, which concentrates the magnetic field between the opposing medial tips for EPR detection.
The key technical points are:
1. The planar inverse anapole microresonator creates a localized magnetic field between opposing medial tips
2. This concentrated field is generated by subjecting the device to microwave radiation
3. The microresonator can be used for inductive-detection EPR spectroscopy applications
