In other words, the quality factor, Q, gives a direct measure of the cavity resonance lifetime.
However, the detailed temporal dynamics of cavities and their lifetime occupancy rates and survival are not usually known which makes it difficult to assess the actual significance and full impact of primary cavity-breeders.
In this study, we monitored cavities in a large forest landscape, covering the full lifetime of cavities.
The total switching time is expected to be restricted by the photon lifetime in cavity due to the ultrafast response speed of polymer.
This is a typical feature of highly resonant systems (i.e. effective cavity modes have a long lifetime) since the real part of each pole in the system corresponds to the exponent of decay of each mode.
A proper assessment of the performance of micro-cavities depends on two crucial parameters - which are the resonance quality factor, Q, and the modal volume, V [13] - where the Q-factor value directly determines the photon lifetime within the cavity and the modal volume, V, is the key factor for assessing the impact of the electromagnetic confinement of the mode within the cavity.
The photon lifetime in the cavity (tau_{text{p}}) is given as: tau_{text{p}}^{ - 1} = (c/n_{text{r}} )left[ {alpha_{text{i}} + ln left( {1/R_{1} R_{2} } right)/left( {2L_{text{ca}} } right)} right], (10 where (R_{1}) and (R_{2}) are the cavity mirror reflectivity coefficients and (alpha_{text{i}}) is the internal loss.
The photon lifetime in the cavity of the CFPI can be estimated as follows.
A novel vacuum package design with vacuum buffer cavity was proposed, the vacuum maintaining lifetime could be increased at least 20 times as compared to the ordinary package with the same volume.
Similarly, a statistically significant increased risk for cancer of the oral cavity in the second category of atrazine lifetime use compared with the lowest use category was observed (RR = 2.09; 95% CI, 1.09 3.99).
