传播常数k5) complex propagation constant 复传播常数6) equivalent propagation constant 等效传播常数 1. A formula of the bending loss in negative dispersion optical fiber was presented through calculating the equivalent propagation constant of multi clad fiber. 采用等效传播常数法数值求解负色散波导光纤...
It was recently proposed to fit these data to a formula that contained all the parameters necessary to construct an empirical relation for the wavelength dependence of the propagation constant. The authors report on the feasibility of this technique, using actual measurement data. They discuss the ...

Different sizes of the nanoposts have different effective propagation constant, and thus different phase delay of the transmitted light. Therefore, the phase modulation of the metasurface can be realized by changing the diameter of the silicon nanoposts as shown in Fig. 1f, and the resonant mode...
Noise power in a communication link is given by Equation 27.8, where N is the noise power in watts, T is the temperature in degrees absolute, often taken as 290°G as this corresponds to the normal room temperature of 17°GC and B is Boltzmanns constant (1.38x10−23). (27.8)N=k...
These experiments are performed with the climate chamber located inside an anechoic chamber with a constant temperature of 22 °C and RH of 50%. The temperature and absolute humidity map covered with this analysis is depicted in Fig. 2b. The range cover a part of the conditions studied with ...
Electromagnetic waves, such as visible light, have a constant speed of 3.0 {eq}\times {/eq} 10{eq}^8 {/eq} m/s in a vacuum, Sound waves travel at a speed of 343 m/s in dry air at a temperature of 20{eq}^\circ {/eq}C....
cases; in this case Gf now plays the role of fracture energy of the kink band (area below the stress-contraction curve of the kink bank and above the σY value), and cf the role of the FPZ of the kink band, which is assumed to be approximately constant, governed by material ...
We finish by looking at the higher-symmetry classes 4mm, 422, 4/mmm,4¯2m: for these classes, by (112) we have that formula (162) holds with αk = βk and δk = ϵk and therefore the mode D1 changes into D2. The results obtained in §§.4.1 and 4.2 for the two limit...
