In this work, the second-harmonic component of wavelength modulation spectroscopy is simulated for R(22) CO2 absorption line to investigate the effect of gas temperature and pressure on the modulation index. We found that the optimum value of modulation index, that is 2.2, is not affected by ...
6G–I). Under a bias voltage, electric charges accumulate apart the oxide interfaces, i.e., holes in the p-doped part and electrons in the n-doped part. This accumulation of carriers induces a change in the refractive index in the silicon close to the interface with the oxide. This ...
AM/PM CONVERSION TESTING BY TRANSMITTING HIGH AND LOW AMPLITUDE SIGNALS OF DIFFERENT FREQUENCIES THROUGH THE DEVICE UNDER TEST AND MEASURING THE PHASE MODU... SSC Jr. 被引量: 0发表: 1969年 Micro-contact performance and reliability under low frequency, low amplitude, alternating current (AC) test...
For example, an interface between different refractive indices causes a change in propagation direction of light both in reflection and transmission1. The strength of this effect depends on the difference between the refractive indices Δn and the incident angle6. Large refractive index differences on...
index in each ROI (Fig.1d, e). The negative valence effect was evident in every visual area, including the amygdala and V1 (Fig.1b, d). We also observed reliable, albeit less pronounced, positive valence effects associated with happy facial expressions in many visual areas (Fig.1c, e)...
Modulation Index fΔ=kfAmfΔ=kfAm. Where kfkf is the sensitivity of frequency Modulation and AmAm is the amplitude of baseband signal. 4.1.6 Design of FM modulation and demodulation VCO plays major role in FM signal generation shown in Figure 23. The modulation index determines the volume and...
The expected results of the phase modulation are shown inFig. 15in terms ofpolarization state. The modulation mechanism is based on a high intensity pump source to heat the MoS2thin film to induce a thermo-optic effect. With the change of refractive index in MoS2thin film, the polarization ...

Local gyrification index The local gyrification index (LGI), a three-dimensional extension of the gyrification index, is an automated method to study regional changes in gyrification, which enables a non-biased estimation of whole-brain morphometric changes. The LGI was defined as an area ...
