Numerical models of a graphene coaxial line

The aim of this paper is to present novel research in special numerical models of a coaxial line used for nanoelectronics. These models can be advantageously utilized in the evaluation of electromagnetic parameters, thus helping researchers and designers to solve problems related to nanoelectronics, sensors, and related components. The first of the models of a large periodic structure is designed to test electromagnetic wave propagation within a coaxial line based on a graphene composite. According to the interpretation of the results, basic design changes will be prepared for experimental fabrication of a functional sample. In the described context, the authors also introduce the results of a numerical analysis of the investigated simple nanoelectric line.
