Investigation of Electromagnetic Wave Propagation in Nanocones

The aim of this thorough study is to investigate the behaviour of electromagnetic wave propagation in three distinct nanostructures, each with unique shapes and material compositions. The first nanostructure under scrutiny is a butterfly-shaped nanocone formed by placing two nanostructures side by side. It consists of two nanocons. The second nanostructure is a deltoid-shaped nanocone created in a similar manner, composed of two different nanocones. The third nanostructure is a parallelogram-shaped nanocone constructed by stacking nanocones on each other and made of two different nanocones. These nanostructures differ in shape and material property parameters, each comprising two different materials with specific permeability and permittivity values. To conduct a detailed analysis, the study utilises the nonlocal theory to examine the electromagnetic wave propagation behaviour in these nanostructures. The focus of the analysis is on the travel and reflection of electromagnetic waves at three specific points along the same axis in each structure, allowing for a comprehensive comparison of their behaviours. This in-depth investigation holds significant importance as it seeks to understand the penetration and subsequent propagation of incident electromagnetic waves within nanostructures of varying shapes and material compositions, shedding light on their potential applications in advanced technology and optic science.
