Based on the diffraction effect of the waveguide grating, a hybrid structure of an all-dielectric multilayer film and a sub-wavelength dielectric grating is proposed. The discrete state provided in the sub-wavelength waveguide grating couples with the continuous state provided in the Fabry-Perot cavity (F-P cavity) containing the photonic crystal to form a Fano resonance. The relationship between the structural parameter and the incident angle is analyzed by numerical simulation.

Mass point-spring model is one of the commonly used models in virtual surgery. However, its model parameters have no clear physical meaning, and it is hard to set the parameter conveniently. We, therefore, proposed a method based on genetic algorithm to determine the mass-spring model parameters.

A new diamond-based variable spring-mass model has been proposed in this study. It can realize the deformation simulation for different organs by changing the length of the springs, spring coefficient and initial angle. The virtual spring joined in the model is used to provide constraint and to avoid hyperelastic phenomenon when excessive force appears.
