Comparing the Buckling Strength of Spherical Shells With Dimpled Versus Bumpy Defects
Pedro Miguel Nunes Pereira de Almeida Reis, Fani Derveni, Arefeh Abbasi
We investigate the effect of defect geometry in dictating the sensitivity of the critical buckling conditions of spherical shells under external pressure loading. Specifically, we perform a comparative study between shells containing dimpled (inward) versu ...
ASME2023Application of ray methods to one-dimensional site response of inhomogeneous soil deposits
The technique referred as ray approximation treats wave propagation in a heterogeneous medium at the infinitely small wavelength limit. This classic simplification allows useful approximate analytical results to be obtained in cases where complete descript ...
2022Inverse-Designed Narrowband THz Radiator for Ultrarelativistic Electrons
Rasmus Ischebeck, Benedikt Hermann
THz radiation finds various applications in science and technology. Pump-probe experiments at free-electron lasers typically rely on THz radiation generated by optical rectification of ultrafast laser pulses in electro-optic crystals. A compact and cost-ef ...
AMER CHEMICAL SOC2022Ultra-Small Bent Meta-Waveguide Filters
Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam
This paper demonstrates the capability of locally resonant metamaterials (LRMs) for creating compact metallic waveguide E- and H-bends, which are simultaneously working as bandpass filters. For creating these bent meta-filters, we use composite pin-pipe wa ...
IEEE2022Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation
Olivier Martin, Karim Achouri, Andrei Kiselev, Marco Riccardi
We review three different approaches for the calculation of electromagnetic multipoles, namely, the Cartesian primitive multipoles, the Cartesian irreducible multipoles, and the spherical multipoles. We identify the latter as the best suited to describe th ...
AMER PHYSICAL SOC2022Magnetic force microscopy contrast formation and field sensitivity
The magnetic force microscope (MFM) is an established experimental tool for imaging stray fields with high spatial resolution and sensitivity. The MFM contrast can however contain contributions from the sample topography, variations in the surface Kelvin p ...
2022Thermally reconfigurable metalens
Giulia Tagliabue, Fateme Kiani Shahvandi, Anna Archetti, Theodoros Tsoulos, Nathanaël Restori, Ren-Jie Lin
Reconfigurable metalenses are compact optical components composed by arrays of meta-atoms that offer unique opportunities for advanced optical systems, from microscopy to augmented reality platforms. Although poorly explored in the context of reconfigurabl ...
