3.4 Gbit/s visible optical wireless transmission based on RGB LED

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
