We present a concise derivation of geometric optics in the presence axionic fields curved space-time. Whenever light can be described via (the eikonal approximation), only difference to situation without field is phenomenon achromatic birefringence. Consequently, redshift and distance estimates based on propagating rays, as well shear magnification due gravitational lensing are not affected by ...

We discuss how small-scale density perturbations on the Fresnel scale affect amplitudes and phases of gravitational waves that are magnified by lensing in geometric optics. derive equations connect with amplitude phase fluctuations to show such perturbative wave optics effects significantly boosted presence macro model magnifications can easily be observed for highly waves. expected signals due...

Pinhole camera model is a simplified subset of geometric optics. In special cases like the image formation of the cone (a degenerate conic section) mirror in an omnidirectional view catadioptric system, there are more complex optical phenomena involved that the simple pinhole model can not explain. We show that using the full geometric optics model a true single viewpoint cone mirror omni-direc...

We construct a numerical scheme based on the Liouville equation of geometric optics coupled with the Geometric Theory of Diffraction (GTD) to simulate the high frequency linear waves diffracted by a half plane. We first introduce a condition, based on the GTD theory, at the vertex of the half plane to account for the diffractions, and then build in this condition as well as the reflection bound...

Charged particle optics, the description of trajectories in vicinity some optical axis, describe imaging properties optics devices. Here, we present a complete and compact charged employing perturbative expansion Hamiltonian mechanics. The derived framework allows straightforward computation transversal longitudinal (chromatic) static dynamic devices with straight curved axes. It furthermore gi...
