Signal Routing by Dispersive Medium
Abstract
A concept of signal routing circuit for the internet or telecommunication system are proposed, by making use of dispersion of the medium in the circuit. Dispersive medium changes its electric constants like dielectric permittivity. Wave propagation in the dispersive medium such as silica glass and silver are demonstrated numerically to show the medium behaves different transmission characteristics. Finally, a model of signal routing system is proposed by making use of the amplitude/frequency dependencies, which is free from electric-optical (E/O) or O/E conversion with time delay and is also free from signal labeling by substitutive use of the signal amplitude or the frequency range.
