Focal spot measurement of millimeter wave dielectric lens antenna by infrared thermal imaging method;

Effect of smoothing by spectral dispersion on the spatial spectrum of focal spot

Objective To improve HIFU focal spot accuracy.

Numerical simulation of pyramdal tip entirely coated with Ag film with focusing spot at nanometer scale;

Based on main compositions of the tar spot formed on polyester fabric during dyeing and its principle of forming,a high - effciency tar spot removing agent has been developed, thus solving the problem which occurs frequently in polyester dyeing.

Precise design of the focused spot and its performance analysis;

For improving the uniformity of the focal spot in the inertial confinement fusion(ICF) experiments,we simulated the effects of the different spectral shapes of broadband light with the focused spot through phase plate,such as random phase plate(RPP) or continuous phase plate(CPP), and the uniform bandwidth and maximal dispersive angle.
