“…After 25 iterations the optimization code gives f low = 1.53 GHz and f high = 3.86 GHz, the dimensions of EBG unit cell are obtained as b = 18.5 mm, g = 7.4 mm, w = 0.9 mm, M = 2, N = 4. A planar EBG structure has been implemented using metaheuristic optimization algorithm, named firefly algorithm (FA) to mitigate SSN in PCBs [15]. Fig.…”
