This paper examines how best to associate quantum states of a single particle to different modes of a narrowly collimated beam of classical radiation modeled in the paraxial approximation. Our ...

Abstract: This paper presents the study of the two methods for the beam-steering planar metasurface antennas based on optical Risley Prism scan theory: paraxial approximation and phase gradient ...

In this notebook we reproduce Figures 2a, 2b and 3 in a Jupyter notebook. Abstract: Analytic expressions for the fields of a tightly focused Gaussian laser beam are derived, accurate to ε11, where ε ...

ABSTRACT: This paper is mainly devoted to application of the Gaussian beam summation technique in electromagnetic simulations problem. Gaussian beams are asymptotic solutions of the Helmholtz equation ...
