The exposure of MRI staff to SMFs and RF fields in the MRI units happen as a result of their induced movement in the MRI room during patients’ examination. Exposure to SMFs among health care workers has been associated with vertigo, nausea, increas

Magnetic resonance imaging (MRI) staff is exposed to a complex mixture of electromagnetic fields from MRI units. Exposure to these fields results in the development of transient exposure-related symptoms. This study aimed to investigate the exposure

Two injection-locked 2:1 frequency dividers for automotive radar applications achieve locking ranges from 82 to 94.1 GHz and from 34.3 to 42.1 GHz and consume 4mW and 8.4mW, respectively. The cascade of the two dividers can be locked from 79.7 to 81.
