Microwave dielectric properties of horticultural peat products [PDF]
Mires and Peat, 2007 The microwave dielectric properties of horticultural peat and compost peat were measured with a HP85107C network analyser in conjunction with a HP85070B open-ended coaxial dielectric probe for the frequency range 0.5–20 GHz.

Physical Mechanisms Underpinning the Vacuum Permittivity
Physics, 2023 The debate about the emptiness of space goes back to the prehistory of science and is epitomized by the Aristotelian ‘horror vacui’, which can be seen as the precursor of the ether, whose modern version is the dynamical quantum vacuum. In this paper, we suggest to change a common view to ‘gaudium vacui’ and discuss how the vacuum fluctuations fix the ...

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A high‐performance n‐type element for quasi‐solid‐state thermocells has been introduced, outperforming conventional p‐type elements and showcasing the potential to harness body heat as an energy source or power embedded sensors. This advance significantly contributes to waste thermal energy harvesting and wearable technology, paving the way for self ...

, 2000 We describe the use of a near-field scanning microwave microscope to image the permittivity and tunability of bulk and thin film dielectric samples on a length scale of about 1 micron. The microscope is sensitive to the linear permittivity, as well as to

Conductivity and permittivity imaging at 3.0 t [PDF]
Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2012 AbstractTissue conductivity and permittivity are critical to understanding radio frequency (RF) power deposition during magnetic resonance imaging (MRI). These electrical properties are also important in treatment planning of RF thermotherapy methods (e.g., RF hyperthermia).

Effect of modifiers on the barium niobate-calcium ceramics structure
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022 In this work, the ceramic samples Са0,3Ba0,7Nb2O6 pure and with modifying additives (5%) SrTiO3, KTaO3 or LiTaO3 were obtained by solid-phase synthesis. All studied compositions of ceramics revealed the presence of large and small grains.

From topological insulators to superconductors and Confinement
, 2012 Topological matter in 3D is characterized by the presence of a topological BF term in its long-distance effective action. We show that, in 3D, there is another marginal term that must be added to the action in order to fully determine the physical ...

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...
