Axicon lenses with chiral-focusing properties modeling by means of analytical functions
OPTICS AND LASERS IN ENGINEERING（2023）
摘要
•Generation of analytical functions for axicon lens construction and simulation.•Non-linear full-wave simulation in finite differences in the time domain of analytically defined lenses.•Numerical verification of conservation relations in electromagnetic structures produced by the study/generated lenses.•Potential for future studies of vortical properties of asymmetric pulsed electromagnetic structures.
