Electromagnetic-field calculations for irregularly shaped, layered cylindrical particles with focused illumination

Theoretical procedures are presented for the determination of internal and external electromagnetic fields for the plane two-dimensional problem of an arbitrary monochromatic field (e.g., a focused laser light sheet) incident upon an irregularly shaped, layered cylindrical particle. Equations for the arbitrary illumination of a layered circular cylindrical particle are also given as a special case of the general solution.
