frequency selective reflection surface

i want to construct a surface which selectively reflect the desired frequency with high Q. Can any one give me some ideas?

Audio, light, RF, microwave or what?

It is microwave

Its 100% possible with Frequency Selective Surface. You can achieve all filtering responses.

How about backing that statement up with some links

Well I am not sure about this idea but you can make a device instead of surface which can receive all EM waves and will transmit a particular band of freq. to the further level by limiting other frequencies by use of band pass concept.

Refer the paper "Application of Double Layer Frequency Selective Surface for SMPS shielding". FSS is used to block the particular band of EM wave.
