resonant gap
解釋
諧振隙-
Spontaneous emission can be totally suppressed or strongly enhanced depending on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density. several novel phenomena can be obtained. the spontaneous emission displays an oscillatory behavior, classical light localization, photon - atom bound state, nonzero steady - state population and anomalously large vacuum rabi splitting. and localized mode associated with a defect site in an otherwise perfect photonic crystals, acts as a high - q micro - cavity
通過原子上能級與光子頻率帶隙邊緣的相對位置或者光子態密度，可以抑制或增強原子的自發輻射。分析並得到了一些奇異的現象，如自發輻射的諧振子行為、光的局域、單光子?原子局域態、上能級中存在非零穩態原子布居數、類似於真空中的拉比頻率分裂等。 -
Abstract : since piezoelectric resonant filter can not effectively prohibit higher - frequency harmonic, the mechanism of this problem has been discussed by means of a specific example which shows that there exists lots of undesirable resonant frequencies of piezoelectric that would let pass undesirable signals. to solve this problem ， an ameliorated electrostatic mechanical resonant filter is proposed and a specific case is demonstrated. the example of electrostatic resonant micro - bridge asserts that by adjusting the gap of exciting capacitance the higher - frequency vibrating model of micro - bridge cannot be excited based on orthogonal character of intrinsic vibrating shape of micro - bridge, so that this kind of resonant filter can effectively filter out undesirable higher - frequency harmonic

The properties of spontaneous emission depend not only on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density but also on the relative distance of the atomic space position from the sidebrand. and we study other property of spontaneous emission
其性質除了依賴于原子上能級與光子頻率帶隙邊緣的相對位置或光子態密度，還依賴于原子的空間位置與側支距離。並對原子的自發輻射的其它特性進行了分析。 -
By changing the composition of n and in, we can adjust the band gap of galnnas to about 1. 3 m and also make it lattice matched to gaas. it makes the resonant cavity enhanced ( rce ) infrared photo detector based on gaas become possible
通過調節n和in的組分，可以使gainnas的帶隙在1 . 3 m左右，同時使得它與gaas晶格匹配，這為實現gaas基的共振腔增強型（ rce ）紅外探測器和激光器提供可能。 -
Since the coupling line brings about an additive inductance in cutoff waveguide filter, which makes the quality factor bigger and resonant band narrower, it - mode double gap cavities are not more advantageous to achieve wider band than the single gap cavities loaded by cutoff waveguide filters
因此，模雙間隙腔加載截止波導濾波器型輸出迴路並不比單間隙腔加載截止波導濾波器型輸出迴路有更好的帶寬優勢。 -
The full - bridge series resonant converter is verified experimentally by using the designed separate transformer. the experimental results for the 4mm and 10mm transformer air gap are given
對全橋串聯諧振變換器構成的非接觸感應電能傳輸系統進行了實驗驗證，給出了可分離變壓器氣隙分別為4mm和10mm的實驗結果。 -
In addition, the control of spontaneous emission of a three - level atom embedded in photonic crystals was investigated in this paper, because the model of two - level atom is siple. as it shows, the properties of spontaneous emission depend not only on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density but also on the intial atomic state
二能級畢竟是最簡單的模型，故在最後，還對光子晶體中三能級原子的自發輻射特性進行了研究。結果表明，其自發輻射除了依賴于原子上能級與光子頻率帶隙邊緣的相對位置或光子態密度外，還依賴于原子的初始狀態。
