Abstract:
The optical properties of spherical nanoparticles, such as their extinction cross-section and scattering cross-section, play a crucial
role in various fields, including biomedicine, energy, and optoelectronics. In this research, we aimed to develop a MATLAB code
that can calculate and analyze the extinction cross-section and scattering cross-section of spherical nanoparticles. The research
problem was the need for a simple and accurate tool to study the optical properties of spherical nanoparticles, given the complexity
and limitations of existing analytical solutions and numerical simulations.
The objectives of the study were to develop a MATLAB code for the calculation and analysis of extinction and scattering
cross-sections, validate the code against analytical solutions and previous numerical simulations, and analyze the results to gain
insight into the optical properties of spherical nanoparticles.
The code was developed based on the Mie theory, and the results were compared with analytical solutions and previous
numerical simulations. The results showed that the code was simple, accurate, and user-friendly, and provided valuable
information about the optical properties of spherical nanoparticles.
The importance of this research lies in the ability to provide a tool for the calculation and analysis of extinction and
scattering cross-sections, which is crucial for understanding and optimizing the optical properties of spherical nanoparticles. The
results of this research offer new insights into the design and optimization of nanoparticles for specific optical properties and
provide a useful tool for researchers and engineers working in the field of optics and optical materials.
