Manifestation of a nontrivial vacuum in discrete light cone quantization

, 2001
We study a (1+1)-dimensional $\lambda\phi^4$ model with a light-cone zero mode and constant external source to describe spontaneous symmetry breaking. In the broken phase, we find degenerate vacua and discuss their stability based on effective-potential ...

New structure of dielectric resonator with greater separation of higher order modes from fundamental mode [PDF]

International Journal of Electronics and Telecommunications
The paper presents a new dielectric resonator structure that allows to obtain a larger distance between the resonant frequency of TE011 mode and higher resonant modes: HE111, TM011 and EH111.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

In-situ characterization of spurious modes in HE11 transmission lines with a 5-port coupler

EPJ Web of Conferences, 2012
Real-time in-situ measurement of spurious modes in HE11 transmission lines is becoming an important topic for the design of next-generation ECRH installations (e.g. ITER), because the acceptable tolerances for the alignment of the waveguides and coupling

High-Performance Microwave Photonic Transmission Enabled by an Adapter for Fundamental Mode in MMFs

Applied Sciences, 2023
Microwave photonic links (MPLs) have long been considered as an excellent way for radio frequency (RF) transmission due to their advantages such as light weight, high bandwidth, low cost and large spurious-free dynamic range (SFDR).

Exact Casimir interaction between eccentric cylinders [PDF]

, 2006
The Casimir force is the ultimate background in ongoing searches of extra-gravitational forces in the micrometer range. Eccentric cylinders offer favorable experimental conditions for such measurements as spurious gravitational and electrostatic effects ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Lithium Niobate MEMS Antisymmetric Lamb Wave Resonators with Support Structures

Micromachines
The piezoelectric thin film composed of single-crystal lithium niobate (LiNbO3) exhibits a remarkably high electromechanical coupling coefficient and minimal intrinsic losses, making it an optimal material for fabricating bulk acoustic wave resonators ...
