Measuring students’ conceptual understanding of wave optics: A Rasch modeling approach
Physical Review Physics Education Research, 2019 Even graduate physics students have many misconceptions about basic wave optics phenomena. This suggests that there is much room for improvement of the traditional wave optics curriculum.

Physical Review Physics Education Research, 2016 Research has shown that students have tremendous difficulties developing a qualitative understanding of wave optics, at all educational levels. In this study, we investigate how three different approaches to visualizing light waves affect students ...

Weakly lensed gravitational waves: Probing cosmic structures with wave-optics features [PDF]
Physical Review D, 2023 Every signal propagating through the universe is at least weakly lensed by the intervening gravitational field. In some situations, wave-optics phenomena (diffraction, interference) can be observed as frequency-dependent modulations of the waveform of ...

Spin-Wave Optical Elements: Towards Spin-Wave Fourier Optics [PDF]
, 2019 We perform micromagnetic simulations to investigate the propagation of spin-wave beams through spin-wave optical elements. Despite spin-wave propagation in magnetic media being strongly anisotropic, we use axicons to excite spinwave Bessel-Gaussian beams and gradient-index lenses to focus spin waves in analogy to conventional optics with light in ...

Lensing of gravitational waves: Efficient wave-optics methods and validation with symmetric lenses [PDF]
Physical Review D, 2022 Gravitational wave (GW) astronomy offers the potential to probe the wave-optics regime of gravitational lensing. Wave optics (WO) effects are relevant at low frequencies, when the wavelength is comparable to the characteristic lensing time delay ...

Rendering specular microgeometry with wave optics [PDF]
ACM Transactions on Graphics, 2018 Simulation of light reflection from specular surfaces is a core problem of computer graphics. Existing solutions either make the approximation of providing only a large-area average solution in terms of a fixed BRDF (ignoring spatial detail), or are ...

Wave optics lensing of gravitational waves: theory and phenomenology of triple systems in the LISA band [PDF]
Physical Review DWe study lensing of gravitational waves by a black hole in the deep wave optics regime, i.e. when the wavelength is much larger than the black hole Schwarzschild radius.

Collective-Mode Enhanced Matter-Wave Optics.
Physical Review Letters, 2021 In contrast to light, matter-wave optics of quantum gases deals with interactions even in free space and for ensembles comprising millions of atoms. We exploit these interactions in a quantum degenerate gas as an adjustable lens for coherent atom optics.

Wave-optics investigation of branch-point density
Optical Engineering: The Journal of SPIE, 2022 . We use wave-optics simulations to investigate branch-point density (i.e., the number of branch points within the pupil-phase function) in terms of the grid sampling.

On the wave optics effect on primordial black hole constraints from optical microlensing search [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Microlensing of stars, e.g. in the Galactic bulge and Andromeda galaxy (M31), is among the most robust, powerful method to constrain primordial black holes (PBHs) that are a viable candidate of dark matter. If PBHs are in the mass range $M_{\rm PBH} {\,
