The response of LPWG sensor to ambient refractive index change is simulated by studying the shift of resonance wavelength caused by the corresponding change of effective refractive index of a certain higher-order mode.

Its resonance wavelengths shift towards the direction of longer wavelength with reduced cladding diameter.

Bending can be an easy modulation of fiber grating抯 resonance wavelength.

The relation between resonant wavelengths and film optical parameters of triple-clad long-period fiber grating;

A study of resonant wavelengths of long period fiber gratings;

In order to reduce the effects of the ambient temperature variations on the resonant wavelength of the Long-Period Fiber Grating(LPFG) devices in communications,a scheme for the compensation of its drift is designed,i.

It is found that the solution of subwavelength resonance is highly dependent on the product of the transversal and longitudinal permeabilities,and there exist more than one for the subwavelength resonance in most cases.

In order to design RF coupling loop for superconducting quarter wave resonator,based on electromagnetic field distribution simulated by 3D electromagnetic field code,position and deepness into cavity of coupling loop were calculated,and the coupling strength of coupling loop at certain bandwidth was specified.
