A wedge cavity within two metallic plates is suggested by filling half of the cavity with a photonic crystal with a negative effective index. The eigen frequencies and quality factors of the modes are studied with the finite element method. Phenomena associated with this open wedge cavity are explained physically. A potential application of this novel cavity as a gas sensor is also studied
