A highly accurate measurement of resonator $Q$-factor and resonance frequency

open access: yes, 2018
The microwave cavity perturbation method is often used to determine material parameters (electric permittivity and magnetic permeability) at high frequencies and it relies on measurement of the resonator parameters.

Adult Education Confronting White Christian Nationalism: A Thematic Analysis

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT As a way to conclude, this article elaborates key themes that emerged from the collected articles in this volume. Each article carries its own important message about the role of adult education in confronting White Christian nationalism, while here, Prins and Carr‐Chellman offer a thematic interpretation of the volume as a whole. These themes

Selective active resonance tuning for multi-mode nonlinear photonic cavities [PDF]

open access: yesarXiv, 2023
Resonant enhancement of nonlinear photonic processes is critical for the scalability of applications such as long-distance entanglement generation. To implement nonlinear resonant enhancement, multiple resonator modes must be individually tuned onto a precise set of process wavelengths, which requires multiple linearly-independent tuning methods.

Cooling of a Nanomechanical Resonator in the Presence of a Single Diatomic Molecule

open access: yes, 2015
We propose a theoretical scheme for coupling a nanomechanical resonator to a single diatomic molecule via microwave cavity mode of a driven LC resonator.

The Case for Procopiu’s Quantum [PDF]

open access: yesMemoirs of the Scientific Sections of the Romanian Academy, 2022
The general traits of the Planck’s quantization procedure for the case of light are considered. The Procopiu’s quantization is presented as a result of this quantization procedure, only applied not to light, but to matter structures.

Unlearning and Deradicalizing From White Christian Nationalism: Implications for Adult Learning and Education

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Since the January 2021 attack on the US Capitol, the influence of White Christian nationalism (WCN) has become even more pronounced and concerning. Adult educators and the public need a better understanding of whether and how WCN can be unlearned, and the roles ordinary citizens and adult educators can play in this process.

Coupled-Resonator Optical Near-Field Lithography [PDF]

open access: yesarXiv, 2008
The problem of pattern formation in resonantly-enhanced near-field lithography by the use of dielectric or plasmonic planar resonators is investigated. Sub-diffraction-limited bright or dark spots can be produced by taking advantage of the rotational invariance of planar resonators.

Ultrasensitive vibrational resonance induced by small disturbances [PDF]

open access: yesarXiv, 2023
We have found two kinds of ultra-sensitive vibrational resonance in coupled nonlinear systems. It is particularly worth pointing out that this ultra-sensitive vibrational resonance is a transient behavior caused by transient chaos. Considering long-term response, the system will transform from transient chaos to periodic response.

Dual-Band Metamaterial Microwave Absorber using Ring and Circular Patch with Slits

open access: yesAdvanced Electromagnetics, 2023
This paper proposes a dual-band metamaterial microwave absorber operating at 2.5 GHz and 5.8 GHz. The absorber consists of a ring and a circular patch with slits resonator structures printed on a FR4 dielectric substrate backed by a ground layer.

GAS-DISCHARGE LASERS OF THE TERAHERTZ RANGE [PDF]

open access: yesРадиофизика и электроника, 2017
The terahertz (THz) frequency range now attracts much attention of researchers and consumers in connection with many possibilities of using it for solving a number of practical problems in science, technology and medicine.
