The diagram of the flat lens is depicted in Fig. 7a, where two nanostrips are aligned in parallel to handle a medium-scaled POPA. The near-field distributions in the xoz plane and at a cut-plane 3.6 μm above the polymer film are shown in Fig. 7b and c, respectively. As seen ...
Draw a diagram of the situation. Labeling the diagram is useful. Step 5. Make a list of what is given or can be inferred from the problem as stated (identify the knowns). Step 6. Solve the appropriate equation for the quantity to be determined (the unknown), and enter the knowns. ...
4. How to derive the new thin lens model 1/f = 1/v + 1/b: similar to m=b/v: b=(1+m)×f: v=(1+1/m)×f: N=1/(2×sin(θ)): numerical aperture This simple equation hides an important concept about light intensity -- that it is inversely proportional (to the square of)...
It was checked experimentally – the resonance frequency is close to the fr value obtained when l in equation (17) is replaced with b, see fig. 14, curves 1, 2, in contrast to the straight petals, when the fr value is determined by their length (curve 3). www.intechopen.com MEMS ...
The bulk modulus was calculated by fitting the Birch-Murnaghan equation of state with the energy-volume data points of the supercells. The Young’s modulus was derived from the elastic constants, where the details were presented by Reeh et al.45. The Poisson’s ratio was calculated from the...
(a) The magnetoconductivity of sample CA1 (hole circle) vs magnetic field in B⊥ E at temperature from 2 K to 150 K along with fitting (red solid curves) to the Equation 2. (b) The dephasing length vs temperature. (c) Temperature dependent parameter α with B⊥ E or...
water nanolayer, the capillary force is nonnegligible and contributes to the dynamic evolution of buckles. The capillary force, which is mainly ascribed to the negative pressure induced by the curvature of the water nanolayer (Fig.3d, inset)40, can be estimated by the following equation: ...
