Effective Permittivity of a Statistically Inhomogeneous Medium with Strong Permittivity Fluctuations [PDF]
Progress In Electromagnetics Research, 2004 Most previous multiple-scattering theories for electromagnetic waves in strongly fluctuating media are limited by the assumption of statistical homogeneity of media. In the paper, a lossy electrically isotropic random medium is considered whose mean permittivity distribution, as well as the multipoint permittivity's moments are invariant under ...

Microwave processing and permittivity measurement of thermoplastic composites at elevated temperature [PDF]
, 1999 [Abstract]: The material properties of greatest importance in microwave processing of a dielectric are the complex relative permittivity ε = ε′- jε″, and the loss tangent, tan δ = ε″/ ε′.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Surface-wave propagation on a grounded dielectric slab covered by a high-permittivity material [PDF]
, 2000 A grounded dielectric slab covered by a higher permittivity material would not normally be expected to support surface waves. This conclusion must be modified when the covering material is sufficiently lossy.
