FIG. 4.

Variation in the leaky power and stored energy coefficients for the bar resonator as a function of the resonant frequencies varied with the bar width . The insets show the polarization occurring on the attached region between the resonator and the PC strips. Left inset: displacement field projected on the plane. Right inset: displacement in the -direction calculated along the vertical central line of the attached region. The displacement in the -direction is normalized by its maximum value.
