diffractive phase elements(DPE’s)是什么意思?越详细越好,还有它跟fractional Fourier transform (FRFT)的关系 求翻译Nevertheless, diffractive phenomena in photonic crystals can lead to the excitation of waves for which phase and group velocities are reversed in the same manner as in negative index metamaterials. phase-to-phase phase是什么意思 “phase out ” PHASE是什么意思 The Technicolor Phase 中文翻译 the technicolor phase 翻译berry phase online phase 怎么翻译 Three-phase inverte phase-lockable 翻译 phase什么意思 H.PHASE什么意思 phase cheung是什么意思 phase me 什么意思 Head phase 什么意思 phase auto-adjustment是什么意思
