Area of Science:

  • Electromagnetics and Optics
  • Computational Physics
  • Surface Science

Background:

  • Analyzing optical scattering from rough surfaces is crucial for understanding wave-matter interactions.
  • Existing methods may face limitations in accuracy or computational efficiency for complex surfaces.

Purpose of the Study:

  • To develop and validate a novel hybrid approach for analyzing optical scattering patterns from rough surfaces.
  • To investigate the influence of surface properties and incident wave characteristics on scattering behavior.
  • To compare the accuracy and efficiency of first-order and second-order geometrical theory of diffraction-ray tracing (GTD-RT) methods.

Main Methods:

  • A new algorithm combining geometrical theory of diffraction (GTD) and ray tracing (RT) is proposed.
  • A Fresnel equation-based model determines scattered power distribution (reflection and transmission).
  • The approach accounts for incident wave polarization and multi-bounce scattering events.

Main Results:

  • Numerical results demonstrate the influence of surface granularity, incidence angle, and refractive index on scattering patterns.
  • The first-order GTD-RT method achieves an average error of less than 2.5%, offering a practical solution.
  • Second-order GTD-RT shows marginal accuracy improvement for rough surfaces but with higher computational cost.

Conclusions:

  • The first-order GTD-RT method provides an efficient and accurate solution for optical scattering analysis on rough surfaces.
  • The proposed model's accuracy is validated against empirical data and established methods like Geometrical Optics (GO).
  • This hybrid approach offers a reliable tool for characterizing electromagnetic wave scattering from random rough surfaces.
