Channel Modeling and Capacity Analysis for Electromagnetic Wireless Nanonetworks in the Terahertz Band
Nanotechnologies promise new solutions for several applications in the biomedical, industrial and military fields. At the nanoscale, a nano-machine is considered as the most basic functional unit which is able to perform very simple tasks. Communication among nano-machines will allow them to accomplish more complex functions in a distributed manner. In this paper, the state of the art in molecular electronics is reviewed to motivate the study of the Terahertz Band (0.1- 10.0 THz) for ElectroMagnetic (EM) communication among nano-devices. A new propagation model for EM communications in the Terahertz Band is developed based on radiative transfer theory and in light of molecular absorption.
