Epsilon-near-zero (ENZ) media have been very actively investigated due to their
unconventional wave phenomena and strengthened nonlinear response. However, the …

In this study, we report enhancement of terahertz (THz) radiation with indium-tin-oxide (ITO)
thin-film deposited on semi-insulating gallium arsenide substrate (SI-GaAs). The amplitude …

Optical tunability is demonstrated with multi-metal hyperbolic metamaterial (HMM) structures
on varying substrate surfaces. A systematic uniaxial modeling methodology is adapted from …

Oxygen vacancies in indium tin oxide (ITO) thin films provide a direct route to effectively tune
the free electron density and thereby, controlling the epsilon-near-zero (ENZ) cut-off …

Film thickness plays a crucial role in determining the position and depth of lossy mode
resonance (LMR). Herein, we explore the overall film thickness dependency of LMR …

The practical application of materials with epsilon-near-zero (ENZ) characteristics heavily
depends on the quality of real-world ENZ materials, considering factors like material losses …

In this study, we report enhancement of terahertz (THz) radiation with indium-tin-oxide (ITO)
thin-film deposited on semi-insulating gallium arsenide substrate (SI-GaAs). The amplitude …

Surface-enhanced infrared absorption spectroscopy (SEIRAS) is an increasingly popular
analytical technique for studying molecular adsorption, finding applications in catalysis …
