Radio frequency heating and material processing using carbon susceptors. [PDF]

Nanoscale Adv, 2021
Carbon nanomaterials have been shown to rapidly evolve heat in response to electromagnetic fields. Initial studies focused on the use of microwaves, but more recently, it was discovered that carbon nanomaterial systems heat in response to electric fields

Role of moisture content, temperature, and frequency on dielectric behaviour of red lentil and Kabuli chickpea in relation to radio frequency heating

Applied Food Research, 2022
Dielectric constant (ε′) and loss factor (ε″) of lentil (grain and flour) and chickpea (split and flour) were determined over four moisture content (MC), seven temperature, and seven frequency using a computer-controlled precision LCR meter built for ...

Spectral features of ionospheric plasma waves excited by powerful HF radio waves radiated at frequencies near electron gyroharmonics and F2-layer critical frequency

Solar-Terrestrial Physics, 2023
We present the result of the studies into characteristics of high-latitude ionospheric F-region longitudinal plasma waves (Langmuir and ion-acoustic), caused by the impact of powerful HF radio waves of ordinary (O-mode) or extraordinary (X-mode ...

Effects of geometry and orientation of food products on heating uniformity during radio frequency heating

, 2021
In radio frequency (RF) assisted heat treatment of food products, heating behavior depends on the composition and geometry of a product. In this study, the effect of salt added to a food simulant on its dielectric properties and penetration depth (dp ...
