WebbSlow waves refer to the propagation of electromagnetic waves with phase velocity much smaller than the speed of light, c[16]. This wave behavior can be achieved by changing the constitutive (e,ju) parameters of the medium properties. Of course, the traditional way is to load the medium with appropriate dielectric properties.

Webb3 feb. 2009 · Abstract. Slow waves are the most prominent electroencephalographic (EEG) feature of sleep. These waves arise from the synchronization of slow oscillations in the membrane potentials of millions of neurons. Scalp-level studies have indicated that slow waves are not instantaneous events, but rather they travel across the brain. Webb9 feb. 2024 · The slow wave concept is confirmed from the value of group delay and is found to be enhanced in the slow wave line by 21.21%. Implementation of slow wave also results in a 36.3% increase in the effective permittivity. Parametric studies are conducted to analyze the slow wave phenomenon.
