An Overview of Geometrical Optics Restricted Quantum Key Distribution [PDF]
Entropy, 2021 Quantum key distribution (QKD) assures the theoretical information security from the physical layer by safely distributing true random numbers to the communication parties as secret keys while assuming an omnipotent eavesdropper (Eve).

Geometrical Optics Restricted Eavesdropping Analysis of Satellite-to-Satellite Secret Key Distillation [PDF]
Entropy, 2021 Traditionally, the study of quantum key distribution (QKD) assumes an omnipotent eavesdropper that is only limited by the laws of physics. However, this is not the case for specific application scenarios such as the QKD over a free-space link.

Electric Transverse Emissivity of Sinusoidal Surfaces Determined by a Differential Method: Comparison with Approximation of Geometric Optics [PDF]
International Journal of Differential Equations, 2021 We present in this paper a numerical study of the validity limit of the optics geometrical approximation in comparison with a differential method which is established according to rigorous formalisms based on the electromagnetic theory.

Geometric optics and the “hairy ball theorem”
Results in Physics, 2016 Applications of the hairy ball theorem to the geometrical optics are discussed. When the ideal mirror, topologically equivalent to a sphere, is illuminated at every point, the “hairy ball theorem” prescribes the existence of at least one point at which ...

A discontinuous Galerkin method to solve Liouville’s equation of geometrical optics [PDF]
EPJ Web of Conferences, 2022 We present an alternative method to ray tracing that is based on a phase space description of light propagation. Liouville’s equation of geometrical optics describes the evolution of the basic luminance on phase space.
