Dynamic Manipulation of THz Waves Enabled by Phase-Transition VO2 Thin Film

Chang Lu et al.

Summary: The reversible and multi-stimuli responsive insulator-metal transition of VO2 has attracted significant attention for its potential applications in the dynamic modulation of the terahertz regime. Research on the growth mechanism of VO2 films has led to improved processing and enhanced device compatibility for diverse THz applications. With special focus on the ultrafast modulation phenomenon observed in the photoinduced IMT, ongoing research aims to understand the physical mechanisms underlying the modulation-allowed IMT for THz applications.

Modelling effective electromagnetic properties of composites containing barium strontium titanate and/or nickel zinc ferrite inclusions from 1 to 4 GHz

Xiaojun Zhu et al.

Summary: The study focuses on predicting the behavior of composites containing high dielectric and/or magnetic inclusions at microwave frequencies using commercial finite element software and effective medium theories (EMTs). Modelling results suggest that limited aggregations of high dielectric contrast inclusions may enhance the effective dielectric properties of composites, serving as predictive tools for guiding composite design.

The interplay between monomer formation, nucleation and growth during colloidal nanoparticle synthesis

Tianlong Wen et al.

Summary: Wet chemical methods have succeeded in controlling the size and size distribution of colloidal nanoparticles. Mathematical models were used to simulate the concurrently occurring precursor reaction, nucleation, and growth, revealing that the competition between nucleation and growth determines the characteristics of batch colloidal nanoparticles.
