Determining the effective electrical properties of a multiphase medium is essential for understanding its performance. However, accurately characterizing the internal structure and calculating the effective electrical properties of complex multiphase media can be challenging, often resulting in divergent results from different models. In this study, we propose a connectivity dependent model for mixed media based on the effective medium approximation, which incorporates structural influences.

Recent band structure calculations have suggested the potential for band tuning in the chiral semiconductor Ag AuTe to zero upon application of negative strain. In this study, we report on the synthesis of polycrystalline Ag AuTe and investigate its transport and optical properties and mechanical compressibility. Transport measurements reveal the semiconducting behavior of Ag AuTe with high resistivity and an activation energy of 0.2 eV.

Metamaterial multipolar mode presents a compelling scheme for exploring fundamental properties and technological applications of light-matter interactions due to its strong near field and high quality factor. In this work, we demonstrate strong coupling and mode hybridization between metamaterial quadrupolar mode and molecular vibration in the mid-infrared.

In this paper, a high-frequency lamb wave resonator (LWR) with near zero temperature coefficient of frequency (TCF) is designed, fabricated, and measured. The reported resonator is of a bi-layer structure consisting of lithium niobate (LiNbO or LN) and silicon dioxide (SiO ), and lithographically patterned aluminum (Al) inter-digitated electrode fingers on top of the bi-layer structure.
