The position of SPP for 1D planar periodicity depends on the grating period, L, and corresponds to the condition of the momentum conservation law (the wave vectors matching) [17]: k_{SPP} = m(2pi /L)+(2pi /lambda)sin theta, (1).
In this article, a method to accurately control the period of subwavelength planar holographic grating which was used as a sub-layer of the guided mode resonance filter is investigated.
Results show that utilizing a convex lens placed in the exposure position can cause the adjusting of the period of subwavelength planar grating more convenient in the holographic optical path during the fabrication process.
Figure 2b e shows the planar geometry of the four periods of the channel (corresponding to slices 1, 2, 3, and 4, respectively, in Fig. 2a).
a The model perpendicular to the channel, b e the planar geometry of the four periods of the channel (corresponding to slices 1, 2, 3, and 4), f a 20 Hz Ricker wavelet synthetic section (corresponding to (a)), g corresponding to slice A, and h corresponding to slice B. Local diachroneity on stratal slices can be removed by non-linear processing.
a The simulated absorption spectra of the 300-nm period structure and the planar reference over the wavelength range from 300 to 900 nm.
The bundle array of CNT-SiNW heterojunctions exhibits relatively stable emission performance with a current fluctuation of about 10% over a 12-h period, as compared to planar CNT-SiNW counterparts.
We rely on the standard technology of gap-tunable planar hybrid undulators, and choose the period of 2.3 cm and the minimum gap of 0.9 cm; total length of the undulator system is 34.5 m.
The polytypic M2B phase is mainly composed of C16, Cb and Ca structural variants, in which planar defects and the resultant long period stacking order (LPSO) structure are identified.
For a pipe with an end-mass, similarly to a plain pipe, three-dimensional period oscillations can be reduced to planar ones.
