Penetration Depth Reduction with Plasmonic Metafilms [PDF]

open access: yesACS Photonics, 2019
In many optical systems, including metal films, dielectric reflectors, and photonic crystals, electromagnetic waves can experience evanescent decay. The spatial length scale of such decay defines the penetration depth. The ability to reduce the penetration depth is important for a number of applications in free-space and integrated photonics.

Penetration Depth of the Scanning Acoustic Microscope [PDF]

open access: yesIEEE Transactions on Sonics and Ultrasonics, 1985
A definition for the penetration depth of the scanning re- flection acoustic microscope is given. With this definition it is possible to calculate the penetration depth of a given lens geometry for a given material. The penetration depth depends on the elastic parameters of the object, the signal-to-noise ratio, and the operation frequency of the ...

Evaluation of penetration depth of near-infrared irradiation generated by tunable ultra-short pulsed laser in ex vivo samples of mouse head [PDF]

open access: yes, 2022
Optogenetic research has opened up the possibility to control neurons that will help detect and treat neurological diseases in the early stage. Treatment of dysfunctions requires exposure to a partial neural network accessible through the absorption of ...

Magnetic penetration depth and T_{c} in superconducting nickelates

open access: yesPhysical Review Research, 2020
We compute the nominal magnetic penetration depth of RNiO_{2} (R=La, Nd) from first-principles calculations and discuss the results in relation to the superconducting T_{c}.

Hybrid layer difference between sixth and seventh generation bonding agent

open access: yesDental Journal, 2006
Since etching is completed at the same stage as priming and bonding, when applying the sixth and seventh generation bonding, the exposed smear layers are constantly surrounded by primer and bonding and cannot collapse.

Soil Density in Traditional Mouldboard Tillage

open access: yesActa Technologica Agriculturae, 2023
Until recently, mouldboard ploughing was used as the main tillage in almost the entire territory of Ukraine and Russia. However, mouldboard technologies contribute to the formation of a “plough pan”, which contributes to additional soil compaction.

Measuring the strength of brittle materials by depth-of-penetration testing [PDF]

open access: yes, 2010
Based on an energy conservation model, the strength offered by a number of brittle materials has been calculated from depth-of-penetration (DOP) test results. Each material was completely penetrated by a tungsten carbide cored projectile of known kinetic

Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding [PDF]

open access: yes, 2010
One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of operating parameters.

Penetration of a glass-faced transparent elastomeric resin by a lead-antimony-cored bullet [PDF]

open access: yes, 2008
The penetration of the lead antimony-cored 7.62 mm × 51 mm bullet into a glass- faced polyurethane elastomeric polymer resin has been studied. The resulting craters in the resin contained elongated bullet core material that had a significant amount of ...
