Circularly polarized coils
Webright-handed circularly polarized light. Circularly polarized light has angular momentum ±e0 E~ 2kˆ, with the positive sign for left-handed and the negative sign for right-handed. … WebThese linearly polarized coils, which come with 10, 20, and 30 mm inner diameters, allow locally restricted excitation and detection of MR signals. In order to increase SNR of X-nuclei signals as well as to simplify NMR data, some X-nuclei applications require 1 H decoupling capability of the coil.
