(physics) A metamaterial component composed of pair of concentric annular rings with splits in them at opposite ends. The rings are made of a nonmagnetic metal, such as copper, and have a small gap between them.

plural of split-ring resonator

magnetic resonance imaging

(medicine) A technique that uses nuclear magnetic resonance to form cross sectional images of the human body for diagnostic purposes.

(physics) The absorption of electromagnetic radiation (radio waves), at a specific frequency, by an atomic nucleus placed in a strong magnetic field; used in spectroscopy and in magnetic resonance imaging.

(physics, chemistry) A technique, related to nuclear magnetic resonance, that allows detection of transitions of atomic nuclei in the absence of a magnetic field.

(physics) The absorption of radiation by species having unpaired electrons when placed in a magnetic field that is used spectroscopically to detect and study free radicals

plural of electron spin resonance

(medicine) A form of magnetic resonance imaging that records the flow of blood to areas of the brain when the patient is undertaking a specific neural activity.

In a resonant manner.
