Multipolar Decomposition Code for Optical Forces on a Sphere

Matlab code supplements Figure 5 from the publication "Multipolar Origin of the Unexpected Transverse Force Resulting from Two-Wave Interference" by Karim Achouri, Andrei Kiselev, and Olivier J. F. Martin. The code performs a multipolar analysis of optical force based on vector spherical harmonic decomposition for a perfect electric conductor sphere in vacuum. It was authored by Karim Achouri of École Polytechnique Fédérale de Lausanne.

Use Cases

• Analyzing contributions from different multipolar interactions to optical forces based on the vector spherical decomposition described.
• Comparing the force from specific multipole interactions (e.g., electric dipole and quadrupole) with the total force as mentioned in the description.
• Calculating optical forces on perfect electric conductor spheres of different radii using the Maxwell stress tensor framework described.
• Visualizing far-field scattered electric fields for spheres using the referenced Mie scattering software.

Strengths

• Code is directly linked to a peer-reviewed publication, providing academic context.
• Analysis is based on the Mie solution and the Maxwell stress tensor framework, which are established methods.
• The description specifies the analysis of forces resulting from interactions between specific multipoles like electric dipole (px) and electric quadrupole (Qexz).

Limitations

• The dataset is described as code, not a pre-computed data table; row count and file formats are unknown.
• Column-level documentation is absent; data structure must be inferred from the code after download.
• Last update date is unknown; freshness unverified.
