We exploit the properties of surface electromagnetic waves propagating at the surface of finite one dimensional photonic crystals to improve the performance of optical biosensors with respect to the standard surface plasmon resonance approach. We demonstrate that the hydrogenated amorphous silicon nitride technology is a versatile platform for fabricating one dimensional photonic crystals with ...

This article presents a new method for generating low-frequency electromagnetic waves navigation and communication in challenging environments, such as underwater underground. The key concept is to disturb the magnetic energy stored around permanent magnet time-variant fashion. reluctance of medium modulated alter flux intensity direction (disturb energy) order achieve this goal. nonlinear prop...

This paper describes a novel technique which has the potential to make a significant impact on the mapping of the human brain. This technique has been designed for 3D full-wave electromagnetic simulation of waves at very low frequencies and has been applied to the problem of modeling of brain waves which can be modeled as electromagnetic waves lying in the frequency range of 0.1–100 Hz. The use...
