A Microwave Frequency Range Experiment for the Measurement of Snow Density and Liquid Water Content

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
This article presents a new nondestructive characterization system for the extraction of both snow density and liquid water content (LWC). The experiment primarily measures the relative complex permittivity of snow ($\overline {{{\boldsymbol{\varepsilon }

Finite Element Analysis for Complex Permittivity Measurement of a Dielectric Plate and Its Application to Inverse Problem [PDF]

The resonant frequency and unloaded quality factor of a cylindrical cavity resonator are computed accurately by using the axisymmetric finite element method. Here the loss of both a dielectric sample and a shielding conductor is taken into account.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Thickness optimization of a double-layered microwave absorber combining magnetic and dielectric particles

Materials Research Express, 2021
The purpose of this study is to optimize the thickness of the double-layered microwave absorber for obtaining the highest absorption. The graphenic-based carbon compounds and Fe _3 O _4 magnetic particles were combined to fabricate the double-layered ...

Embedded Ferroelectric Nanoclusters Can Drive Polarization Reversal in a Non‐Ferroelectric Polar Film via the Proximity Effect

Advanced Functional Materials, EarlyView.
Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Analysis of glucose‐dependent dielectric properties of aqueous‐based solution: A proof of concept

IET Science, Measurement & Technology, 2021
In spite of widespread research and exploration, the status of non‐invasive blood glucometer for diabetic people is far from satisfactory. This unlocks the prospect for further significant research in the field of non‐invasive blood glucose sensing.
