A coupled dielectric-metal metasurface (CDMM) consisting of amorphous silicon(a-$\textit{Si}$) rings and subwavelength holes in $\textit{Au}$ layerseparated by a $\textit{SiO}_{2}$ layer is presented. The design parameters ofthe CDMM is numerically optimized to have a polarization independent peaktransmittance of 0.55 at 1540 nm with a Full Width at Half Maximum ($FWHM$) of10 nm. The filter also has a 100 nm quite zone with $\sim 10^{-2}$transmittance. A radiating two-oscillator model reveals the fundamentalresonances in the filter which interfere to produce the electromagneticallyinduced transparency (EIT) like effect. Multipole expansion of the currents inthe structure validates the fundamental resonances predicted by thetwo-oscillator model. The presented CDMM filter is robust to artifacts indevice fabrication and has performances comparable to a conventionalFabry-P\'{e}rot filter. However, it is easier to be integrated in image sensorsas the transmittance peak can be tuned by only changing the periodicityresulting in a planar structure with a fixed height.
