An attempt is made to control microwave propagation in a metallic photonic crystal (MPC) making defaults or plasma columns. Electromagnetic band gaps (EBGs) are studied with defaults or holes in different configurations of MPC. Further, a plasma column is formed in defaults to increase the controllability and tunability of MPC. Moreover, a plasma column is also formed between microwave transmitter and MPC. Findings of this study show that flat and forbidden bands can be controlled in such a way that the negative and positive refractions can be achieved at particular angles. Hence, it reveals importance of plasma to enhance the controllability of microwave propagation in photonic crystals. © 2011 Wiley Periodicals, Inc.
