In the past, the featured finite difference time domain (FDTD) software was used to simulate a multilayer planar structure light absorber’s design and obtain the optimal thickness for each layer through this software. In this study, we employed the thickness values obtained from FDTD in another software, COMSOL, for simulation. Subsequently, we compared the absorptivity simulated by COMSOL with that obtained through FDTD. Due to the different computational methods of the two software tools, the absorptivity simulated by COMSOL using the layer thickness values from FDTD became less accurate. As a result, the thickness of each layer was fine–tuned to identify the optimal parameters for each layer. The optimized parameters with the absorptivity values in the present study were compared to previous results. Variations in the optimal thickness for each layer when utilizing these two software applications were found with different results.

    Formation of Fine Line Circuits on Ferrite Substrate by Laser Direct Structuring Technology

    by Hong-Bing Tsai*, Syun-Yi Lai,, Quoc-Thai Pham and Hung-Ta Wu
    AFM 2023, Vol 3, Issue 4, 9-15, https://doi.org/10.35745/afm2023v03.04.0002 - Published on November 28, 2023

    Abstract

    The technology of laser direct structuring (LDS) on ferrite substrates was evaluated for the fabrication of fine-line circuits. The LDS technology involves laser activation followed by electroless copper plating. A sieving pattern was scanned by the near IR laser on the ferrite substrates, and electroless copper plating was carried out. The results showed that the LDS technology applied to Ni-Zn-Cu-ferrite films. Appropriate laser activation conditions were chosen to engrave a contrast pattern o...

    Development of Nanoporous Nickel Oxide Materials as Electrodes for Supercapacitors

    by Yang-Ming Lu, Yen-Ching Lin and Ting-Yi Liu
    AFM 2023, Vol 3, Issue 4, 16-20, https://doi.org/10.35745/afm2023v03.04.0003 - Published on December 30, 2023

    Abstract

    As a potential electrochemical energy storage device, supercapacitor has been researched owing to its low weight, excellent power density, outstanding charging rate, and long durability. For the supercapacitor, the electrode material and its morphology determine its overall performance. Nickel oxide (NiO) is a promising material for the electrode because of its low cost, high specific capacitance, and eco-friendly manufacturing process. In this research, we developed a simple and cost-effective ...
