Metalenses that correct chromatic aberration also suffer from reduced focusing efficiency. Here, the authors introduce a Hybrid Achromatic Metalens which merges a metalens and phase plate to offer improved focusing efficiency over a broad wavelength

Autor: Haoyuan Li, Yanwen Sun, Joan Vila-Comamala, Takahiro Sato, Sanghoon Song, Peihao Sun, Matthew H. Seaberg, Nan Wang, J. B. Hastings, Mike Dunne, Paul Fuoss, Christian David, Mark Sutton, Diling Zhu

Publikováno v: Physical Review Research, Vol 3, Iss 4, p 043050 (2021)

Beam splitters and delay lines are among the key building blocks of modern-day optical laser technology. Progress in x-ray free electron laser source development and applications over the past decade is calling for their counterpart operating at the

X-ray free-electron lasers can generate radiation pulses with extreme peak intensities at short wavelengths. This enables the investigation of laser–matter interactions in a regime of high fields, yet at a non-relativistic ponderomotive potential,

Circadian Rhythms in Dinoflagellates: What Is the Purpose of Synthesis and Destruction of Proteins?

Autor: J. Woodland Hastings

Publikováno v: Microorganisms, Vol 1, Iss 1, Pp 26-32 (2013)

There is a prominent circadian rhythm of bioluminescence in many species of light-emitting dinoflagellates. In Lingulodinium polyedrum a daily synthesis and destruction of proteins is used to regulate activity. Experiments indicate that the amino aci

Discrete dipole approximation of gold nanospheres on substrates: Considerations and comparison with other discretization methods

Autor: M. P. Menguc, T. Wriedt, J. T. Hastings, G. M. Huda, E. U. Donev, V. L. Y. Loke

Publikováno v: Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, Vol 89, Iss S1, Pp C1V89S1P060-1 (2011)

We embark on this preliminary study of the suitability of the discrete dipole approximation with surface interaction (DDA-SI) method to model electric field scattering from noble metal nano-structures on dielectric substrates. The refractive index of

Trend-surface analysis revisited—a case history

Autor: P G Sutterlin, J P Hastings

Publikováno v: Computers & Geosciences. 12:537-562

Oil production in the Nichols Field, located in south-central Kiowa County, Kansas was discovered by Gulf Oil Corp. in 1956. The oil-producing zone, which lies on the crests and flanks of a southwest-plunging anticlinal nose, is formed by an updip st
