High Q Resonant Laminate

An elastic steel layer with a relatively high q m significantly increases the resonant enhancement of the me coefficient due to an increased effective q m of the laminate.

High q resonant laminate.

Hence a higher mevc at resonance can be obtained. The three phase me laminates have a low first order bending frequency of 5khz with a resonance enhanced me coefficient of 40v cmoe. This paper experimentally clarifies wide frequency band. The microstrip antenna features high q and higher resonance harmonics which are not integer multiples of the dominant resonance frequency if a circular microstrip antenna cmsa is chosen.

The range of frequencies for which the oscillator resonates is. Sinusoidally driven resonators having higher q factors resonate with greater amplitudes at the resonant frequency but have a smaller range of frequencies around that frequency for which they resonate. It provides a new.

To explore the resonant me response dong characterized the dissipation of material at resonance by introducing the mechanical quality factor q mech however it should be mentioned that when the composite operates in resonant mode there still. Finally due to the nature of high q versus low q effects the type of damping utilized will have a large impact on the success of the method. The metasurface is designed to operate in two complementary modes namely electromagnetically induced transparency and. The theoretical analysis on the resonant me effect of the mp laminate composite is mainly based on the equivalent circuit method proposed by dong et al.

The variation of the hole size of the cuboid allows for the tuning of the resonant anapole mode in the nanoparticles. In this work a dielectric metasurface consisting of hollow dielectric nanocuboids with ultrahigh quality factor is theoretically proposed and demonstrated.

Consequently high q resonators provide huge enhancement to other characteristics of devices exploiting the resonance effects e g material characterization tools 6 9 biological and chemical sensors 10 the latter can detect a single nanoparticle 11 or even a single atom 12 ultralow threshold and super directional lasers 13 14 and so on.

Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator resonator. Meanwhile the effective mechanical quality factor of the laminate is enhanced owing to the high q m of fecunbsib about 1000. In addition if the cabinet wall resonance falls into a frequency range that is excited constantly by music or the human voice i e 100 400hz the resonances will be even more audible. A high performing durable engineered surface used for a variety of vertical and horizontal applications wilsonart s hpl also offers a broad range of attractive patterns and texture possibilities.
