Subcell Treatment of Sloped Interfaces between Debye Materials in the FDTD Method
Journal of Amasya University the Institute of Sciences and Technology, 2020 This paper presents the application of the subcell technique for the treatment of sloped interface in finite-difference time-domain method. The technique is based on the averaging of permittivities in each cell crossed by the material interface.

Comparison of errors and stability in FDTD and FVTD [PDF]
Advances in Radio Science, 2003 The methods of finite-difference time-domain (FDTD) and finite-volume time-domain (FVTD) are well known techniques for solving electromagnetic problems. While for FDTD a number of commercial codes is available there are only few based on FVTD.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching
Advanced Functional Materials, EarlyView.A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Photonic Engineering Enables All‐Passive Upconversion Imaging with Low‐Intensity Near‐Infrared Light
Advanced Functional Materials, EarlyView.A passive upconversion imaging system enables the observation of scenes illuminated by low‐intensity incoherent near‐infrared light from 750 to 930 nm, by converting it into the visible without the use of external power. The upconverter is enabled by triplet–triplet annihilation in a bulk heterojunction, with absorption enhanced by plasmonic resonators
