The extinction cross section is defined as the sum of the absorption cross section and the scattering one which can be expressed as following by using Mie theory4 $${C}_{ext}=\frac{2\pi }{{k}^{2}}\mathop{\sum }\limits_{n=1}^{\infty }\,(2n+1)\mathrm{Re}({a}_{n}+{b}_...
A number of studies, both simulations and experiments, have been carried out to obtain a good performance SPR biosensor. In a simulation study, the Fresnel equation and the transfer matrix method (TMM) can be used to determine reflectance in multilayer SPR structures [29]. ...

Draw the Lewis structure (including resonance structures) for diazomethane (CH2N2). For each resonance structure, assign formal charges to all atoms that have a formal charge. Draw the best resonance structure of the compound on the left. ...
There are several optical modes designed for surface plasmon waves, as shown in Figure 2. Prism coupling mode, known as attenuated total reflection (ATR) mode, is the most commonly used in triggering surface plasmons. Figure 2a shows the prism coupling of the two structures: the Otto structure...
The highest sensitivities can achieve 214.8 Deg/RIU, 210.1 Deg/RIU, 315.5 Deg/RIU and 286.3 Deg/RIU for the structures containing 3-layer MoS2 with 22 nm Al film, 4-layer MoSe2 with 24 nm Al film, 7-layer WS2 with 36 nm Al film and 7-layer WSe2 with 30 nm Al film, respectively...
In contrast, opto-thermal excitation is a more efficient actuation mechanism for suspended resonant structures utilizing thermomechanical coupled [17,18], because it is a non-contact technique that can be implemented at lower micron and nanometer scale without sophisticated material integration. For ...
