研究目的
Investigating the linear electromagnetic interaction between hybrid metallo-dielectric nanostructured targets and laser in visible and IR range for enhancing light absorption and optimizing targets for nuclear fusion purposes, especially the D–D reaction.
研究成果
The study demonstrated the possibility to strongly confine the optical energy within nanometric volumes localized on the target surface with a precise geometrical optimization that enhances the linear coupling between electromagnetic radiation and the nanowire plasmonic array. The designed nanostructured target showed potential for improving optical performances for nuclear-astrophysics applications, particularly in enhancing light absorption for the D–D reaction.
研究不足
The study is based on linear optical phenomena and disregards any thermodynamic effect, including the target destruction dynamic related to the laser pulse duration and the beam power density. The influence of these aspects needs to be experimentally verified.
1：Experimental Design and Method Selection:
Numerical simulations were conducted to investigate the linear electromagnetic interaction between hybrid metallo-dielectric nanostructured targets and laser in visible and IR range. The study focused on optimizing a target based on metallic nanowires (NWs) to enhance light absorption.
2：Sample Selection and Data Sources:
The targets consisted of ordered silver nanowires embedded in an alumina matrix, where the alumina pores on top of the nanowires could be filled with a deuterium-doped oxide.
3：List of Experimental Equipment and Materials:
The study utilized finite element method (FEM) simulation using COMSOL Multiphysics.
4：Experimental Procedures and Operational Workflow:
The simulations involved calculating the electromagnetic power dissipated by the Joule effect on the top surface of the Ag nanowires under s-polarized plane wave excitation.
5：Data Analysis Methods:
The optical response of the nanostructure was analyzed to maximize light absorption in the region where deuterium is located.
