The Interaction of Microwaves with Materials of Different Properties

open access: yesElectromagnetic Fields and Waves, 2019
Electromagnetic radiation, such as microwaves, are all the time reflected, transmitted, and/or absorbed by any kind of matter, glasses, conductors, water, ferrites, and so forth. Magnetic materials absorb greatly microwaves.

Microwave Heating of Water, Ice and Saline Solution: Molecular Dynamics Study

open access: yes, 2006
In order to study the heating process of water by the microwaves of 2.5-20GHz frequencies, we have performed molecular dynamics simulations by adopting a non-polarized water model that have fixed point charges on rigid-body molecules.

Quasi-Coherent Phase-Based Localization and Tracking of Incoherently Transmitting Radio Beacons

open access: yesIEEE Access, 2021
The direct measurement of distance-dependent information between wireless units represents a challenge for wireless locating systems, because it requires the exact time synchronization of separate wireless units.

Universal holonomic quantum gates over geometric spin qubits with polarised microwaves

open access: yesNature Communications, 2018
A microwave shares a nonintuitive phase called the geometric phase with an interacting electron spin after an elastic scattering. The geometric phase, generally discarded as a global phase, allows universal holonomic gating of an ideal logical qubit ...

Characterization of the Amazon Rainforest Backscatter at X-Band Using TanDEM-X Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The radiometric calibration of spaceborne SAR products plays a key role for ensuring a good performance of the whole end-to-end system and requires a precise knowledge of both the radar system and the illuminated target on ground.
