Exceptional points (EPs) -- singularities in the parameter space of non-Hermitian systems where two nearby eigenmodes coalesce -- feature unique properties with applications such as sensitivity enhancement and chiral emission. Existing realizations o

Optical fibers typically confine light through total internal reflection or through photonic bandgaps. Here we show that light can be perfectly guided in optical fibers through a different mechanism based on bound states in the continuum (BICs). In f

We develop a formalism, based on the mode expansion method, to describe the guided resonances and bound states in the continuum (BICs) in photonic crystal slabs with one-dimensional periodicity. This approach provides analytic insights to the formati

During the combined fatigue test of certain engine fan blade,the difficulty was how to combine low cycle fatigue and high cycle fatigue,and applied them to the assessment location of the blade. The modal analysis and test was carried to obtain the na

In order to carry on life determination on certain engine fan blade,high and low cycle fatigue tests were conducted on several specimens. The fatigue characteristic curve( S-N curve,P-S-N curve) was obtained by statistical analysis.The results sh

A type of aero engine compressor blade model was built based on finite element. Dynamics of the clamped constrained blade was obtained by modal simulation and the influence of centrifugal force on the vibration of blades was researched. And then,the
