Abstract
The use of new technologies in electronic warfare is inevitable. One of the new weapons in this field are lasers. Laser weapons destroy a target by directing a laser beam and aiming it at the target. Laser means light amplification by the method of inductive emission of radiation. In this paper, it has been tried to use the features of photonic crystal structures and connect it to the body of air fighters to reduce the destructive power of these weapons to its minimum level. Due to the property of the photonic band gap of photonic crystals and the creation of several waveguides in the dielectric rods, the incident light of the laser is deflected and directed into the waveguides, and the laser light has the least collision with the fuselage. The structure is made of hexagonal lattice, which has the lowest amount of light leakage from the waveguide. Another important feature of the proposed structure is that all the dielectric rods have the same radius, which makes the design and implementation easier..
