Abstract

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 ...

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...
