Asymptotic behavior of Dirichlet series

open access: yesJournal of Mathematical Analysis and Applications, 1981
Let f(z) = C& akelkz be a Dirichlet series which converges absolutely for each z E 6, where lim,+, A, = co. Let S(x,f) = Sup, ]f(x + iy)] for x E N?. In the theory of ordinary differential equations with Dirichlet series as coefficients, the following problem arose (cf.

High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm

open access: yesAdvanced Materials Technologies, EarlyView.
Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

Detection of Hybrid Optical Anapoles in Dielectric Microspheres

open access: yesAdvanced Optical Materials, EarlyView.
In this work, hybrid optical anapoles are detected in dielectric microspehers using dual detection optical spectroscopy. The results show that the excitation of TiO2 microspheres under tightly focused Gaussian Beam illumination leads to the appearence of scattering minima in both the forward and backward directions within specific wavelength ranges ...

Asymptotic Behavior of Solutions to a Vector Integral Equation with Deviating Arguments

open access: yesAbstract and Applied Analysis, 2013
In this paper, we propose the study of an integral equation, with deviating arguments, of the type y(t)=ω(t)-∫0∞‍f(t,s,y(γ1(s)),…,y(γN(s)))ds,t≥0, in the context of Banach spaces, with the intention of giving sufficient conditions that ensure the ...

Evolution of Collective, Radiative Plasmon Coupling in Confined, Soft Colloidal Films

open access: yesAdvanced Optical Materials, EarlyView.
Plasmon resonance coupling is continuously monitored during the uniaxial manipulation of a 2‐dimensional soft colloidal film containing hexagonally arranged spherical gold nanocrystals. This is realized by the in situ spectroscopic investigation of a monolayer of plasmonic core‐shell microgels confined at the air/water interface that is compressed in a

Mitigating Losses in Hyperbolic Asymptotic Eigenmodes

open access: yesAdvanced Photonics Research, EarlyView.
Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced.
