Scaling effect and its impact on wavelength-scale microlenses

Hans Peter Herzig, Myun Sik Kim, Toralf Scharf

We revisit the scaling laws in micro-optical systems to highlight new phenomena arising beyond a conventional optical regime, especially when the size of the system approaches to the operational wavelength. Our goal is to visualize the impact of the scalin ...

HOLiCOW - IV. Lens mass model of HE 0435-1223 and blind measurement of its time-delay distance for cosmology

Frédéric Courbin, Vivien François Bonvin

Strong gravitational lenses with measured time delays between the multiple images allow a direct measurement of the time-delay distance to the lens, and thus a measure of cosmological parameters, particularly the Hubble constant, H-0. We present a blind le ...

H0LiCOW-II. Spectroscopic survey and galaxy-group identification of the strong gravitational lens system HE 0435-1223

Malte Tewes, Georges Meylan, Frédéric Courbin, Vivien François Bonvin

Galaxies located in the environment or along the line of sight towards gravitational lenses can significantly affect lensing observables, and can lead to systematic errors on the measurement of H-0 from the time-delay technique. We present the results of a ...

Synthetic diagnostic for the beam emission spectroscopy diagnostic using a full optical integration

Loïc Hausammann

The beam emission spectroscopy (BES) diagnostic is used to measure fluctuations of electron density in the edge and core of fusion plasmas, and is a key in understanding turbulence in a plasma reactor. A synthetic BES diagnostic for the turbulence simulati ...

Adamts18 deletion results in distinct developmental defects and provides a model for congenital disorders of lens, lung, and female reproductive tract development

Cathrin Brisken, Marian Caikovski, Yakir Guri, Alessandra Piersigilli, Dalya Ataca

The ADAMTS family comprises 19 secreted metalloproteinases that cleave extracellular matrix components and have diverse functions in numerous disease and physiological contexts. A number of them remain 'orphan' proteases, among them ADAMTS18, which has bee ...

Refraction limit of miniaturized optical systems: a ball-lens example

Hans Peter Herzig, Wilfried Noell, Roland Andreas Bitterli, Myun Sik Kim, Toralf Scharf

We study experimentally and theoretically the electromagnetic field in amplitude and phase behind ball-lenses across a wide range of diameters, ranging from a millimeter scale down to a micrometer. Based on the observation, we study the transition between ...

Transition of optical regime in miniaturized optical systems: light interactions beyond the refraction limit

Hans Peter Herzig, Myun Sik Kim, Toralf Scharf

We investigate the transition of optical regimes of miniaturized optical systems using two canonical examples, where the refraction of light limits the system performance. A ball-lens and a solid immersion lens (SIL) are considered, whose refractive respon ...

Lens-based Ka-band antenna system using planar feed

Juan Ramon Mosig, Marc Esquius Morote, Joana Rita Alves dos Santos Silva, Maria Garcia Vigueras

This paper presents a simple, low-cost and compact mobile ground terminal antenna for Ka-band satellite communications that operates in the downlink band (19.7-20.2 GHz). The antenna is composed of a shaped dielectric lens which tilts in front of a planar ...
