How to excite the high Q-factor in metamaterials with BIC?3 answersTo excite a high Q-factor in metamaterials with BIC, several approaches have been proposed in the literature. One method is to use all-dielectric metamaterials, where multiple high Q-factor Fano resonances can be excited by depositing silicon material on a silica substrate and etching air holes in the meta-molecules. Another approach is to engineer high-quality-factor optical resonances in high-index dielectric nanoparticles and all-dielectric metasurfaces by utilizing the concept of bound states in the continuum (BICs). By adjusting the rotation angle of elliptical resonators, a sharp BIC transmission dip can be observed with a high Q-factor. Additionally, the excitation of toroidal multipoles in metamaterials, such as asymmetric split ring resonators (ASRRs), can significantly strengthen the scattering power of toroidal dipoles and increase the Q-factor of the toroidal metamaterial. These approaches provide opportunities to enhance the Q-factor of metamaterials and enable applications in optical devices, biosensors, nonlinear optics, and optical switches.

What are the methods to measure the intrinsic quality factor of a resonator?4 answersThere are several methods to measure the intrinsic quality factor (Q-factor) of a resonator. One method involves measuring the proper Q-factor of a volumetric metal resonator and then calculating the Q-factor of the open dielectric resonator based on the resonance frequency and coupling coefficients. Another approach is to use a general Q-factor measurement system, which includes excitation of the resonator, acquisition of the resulting signal, and signal processing to determine the Q-factor. This can be done in the frequency domain, time-frequency domain, or time domain, with the time domain approach being the only way to conduct an in-situ Q-factor measurement. Additionally, a novel method involves using thermoelastic dissipation (TED) to trim the Q-factor of a 2-axis mode-matched resonator, allowing for independent modification of the Q-factors of each axis.

What are the methods to measure the intrinsic quality factor of a ring resonator?5 answersThere are several methods to measure the intrinsic quality factor (Q-factor) of a ring resonator. One approach is to use a general Q-factor measurement system that includes excitation of the resonator, acquisition of the resulting signal, and signal processing to determine the Q-factor. This method allows for measurements in the frequency domain, time-frequency domain, or time domain, with each approach having its own advantages and limitations. Another method involves using thermoelastic dissipation (TED) to control the Q-factor of a resonator. By carefully designing the resonator and trimming the heat conduction path, the Q-factor can be modified while minimizing changes to the resonance frequency. Additionally, the use of a ring electrode in a quartz crystal microbalance (QCM) resonator has been shown to result in a high Q-factor and good frequency stability.

To enhance housing affordability for Gen Z, a combination of supply, location, financial, tax, and economic policy characteristics should be encouraged. Monetary policy should be carefully considered, as empirical studies show a negative association between interest rate changes and house price changes, cautioning against relying solely on monetary policy to address affordability issues. While reducing housing unit costs is important, there are limits to this approach, necessitating strategies that improve the economic status of low-income groups by reducing household expenditure or boosting incomes. Government intervention in the housing market, particularly through public housing strategies, can facilitate the supply of affordable housing to lower-income households, aligning with the fundamental justification for government involvement based on market characteristics like externalities and imperfect information.Are monotropoideae the only mycoheterotrophic ericaceae?
