The integration of several of these nano-devices into a single entity will enable the development of advanced nanomachines. By means of communication, nanomachines will be able to organize themselves in networks, or nanonetworks, and complete more complex tasks in a distributed fashion, such as wireless nanosensor networks for advanced health monitoring and drug delivery systems, wireless networks on chip for massive multi-core computing architectures and, ultimately, the Internet of Nano-Things. However, traditional communication technologies and techniques cannot simply be reused to enable the communication between nanomachines, due to the capabilities of nano-devices and the physics of the wireless channel. In this context, the objective of this thesis is to establish the theoretical foundations of high frequency electromagnetic (THz) and optical wireless communications at the nanoscale. Imposed by the size constraints of nanomachines, first, a unified mathematical framework is developed to investigate the performance in transmission and reception of metallic nano-dipole antennas at infrared and visible optical frequencies. Starting from the study of the propagation properties of surface plasmon polariton (SPP) waves on the metallic nano-dipoles, a new antenna theory for nano-structures is derived. Motivated by these results, the use of wireless optical communication for on-chip networks is proposed. To assess the feasibility of this paradigm, new frequency and time domain channel models that capture the propagation of optical wireless signals on chip are developed, by combining tools from ray tracing and communication theory. In order to increase the communication distance, there is a need to reduce the system frequency, while still keeping the size of the nano-antennas small.
