Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Multiband-integrated antenna/artificial magnetic conductor
IET Microwaves, Antennas & Propagation, 2011 An artificial magnetic conductor (AMC)-based multiband low-profile antenna for vehicle applications is designed, simulated and measured in this study. The AMC is a simple dual band structure, constructed on a 3.2 mm-thick FR-4 (e r =4.4) board, with the reflection phase and surface wave bandgaps in the 2.0 and 5.8 GHz ranges.

ARTIFICIAL MAGNETIC CONDUCTORS ON WIDEBAND PATCH ANTENNA
Progress In Electromagnetics Research Letters, 2013 The use of Artiflcial Magnetic Conductor (AMC) as a re∞ector in a printed antenna is known to improve the antenna's radiation characteristics. This work investigates the implementation of AMC as a re∞ector on a wideband planar monopole antenna. The investigation is conflned to a basic square unit cell of AMC with four possible variations.
