A Low-Temperature Annealing Method for Alloy Nanostructures and Metasurfaces: Unlocking a Novel Degree of Freedom
Olivier Martin, Christian Santschi, Debdatta Ray, Hsiang-Chu Wang, Jeonghyeon Kim
The material and exact shape of a nanostructure determine its optical response, which is especially strong for plasmonic metals. Unfortunately, only a few plasmonic metals are available, which limits the spectral range where these strong optical effects ca ...
WILEY-V C H VERLAG GMBH2022The Polarity Reversal of Lightning‐Generated Sky Wave
Marcos Rubinstein, Mohammad Azadifar, Wenhao Hou
The polarity reversal of the lightning‐generated first sky wave as a function of the observation distance is studied using a novel approach combining the finite‐difference time domain (FDTD) method and the superposition principle of electromagnetic waves. ...
2020Scaling effect and its impact on wavelength-scale microlenses
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim
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 ...
Spie-Int Soc Optical Engineering2017Binary subwavelength structures that act simultaneously as antireflective and diffractive structure for the mid-infrared wavelength range
Hans Peter Herzig, Grégoire Maxime Smolik
We present a single-layer of binary subwavelength structures designed to reduce Fresnel reflections at an interface while providing an efficient diffractive function. ...
2016On the Plane Wave-Excited Subwavelength Circular Aperture in a Thin Perfectly Conducting Flat Screen
Juan Ramon Mosig, Krzysztof Michalski
The electromagnetic field transmitted by a subwavelength circular aperture in a perfectly conducting screen of infinitesimal thickness and illuminated by an obliquely incident plane wave is analyzed based on the Bethe-Bouwkamp quasi-static model of the fie ...
Institute of Electrical and Electronics Engineers2014Experimental and theoretical study of the Gouy phase anomaly of light in the focus of microlenses
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim, Ali Naqavi
We report on the Gouy phase anomaly of light in the focus of cylindrical and spherical microlenses. The prime subject of our study concerns a discussion of how the very small size of microlenses affects the phase properties of light in their foci. We put e ...
Institute of Physics (IoP) and Deutsche Physikalische Gesellschaft2013Comment on “Encoding many channels on the same frequency through radio vorticity: first experimental test”
Julien Perruisseau-Carrier, Michele Tamagnone
We show that the public experiment held in Venice by Tamburini et al and reported in 2012 New J. Phys. 14 033001 can be regarded as a particular implementation of multiple-input-multiple-output (MIMO) communications and, therefore, has no advantages over e ...
Institute of Physics (IoP) and Deutsche Physikalische Gesellschaft2012Longitudinal-differential interferometry: direct imaging of axial superluminal phase propagation
Hans Peter Herzig, Toralf Scharf, Myun Sik Kim
We introduce and demonstrate a new interferometric method called longitudinal-differential (LD) interferometry, which measures the spatially resolved phase difference of the scattered field by an object relative to the illumination. This method is combined ...
Optical Society of America2012Full-field microimaging with 8 keV X-rays achieves a spatial resolutions better than 20 nm
Fresnel zone plates (450 nm thick Au, 25 nm outermost zone width) used as objective lenses in a full field transmission reached a spatial resolution better than 20 nm and 1.5% efficiency with 8 keV photons. Zernike phase contrast was also realized without ...
Optical Society of America2011Normally Incident Wave Propagation across One Joint Set with Virtual Wave Source Method
Jian Zhao, Gaofeng Zhao, Jianbo Zhu
This paper presents an analytical study on normally incident wave propagation across a joint set. Combined with the displacement discontinuity method (DDM), the virtual wave source method (VWSM) is adopted to take account of multiple wave reflections among ...
