Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications
Advanced Materials Technologies, EarlyView.Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

The influence of temperature on the dielectric properties of siderite [PDF]
Acta Montanistica Slovaca, 2005 The behaviour of studied samples in electric field at microwave frequency is characterised by the real and imaginary part of the complex dielectric constant. Aknowledge of these parameters permits to predict the running of the microwave heating.
