Abstract :
Centered broadwall slot with curved partial height iris is analyzed in this paper. Slot length is optimized for finding out the maximum realized gain by varying iris depth in transverse direction. Maximum of 4.92dB realized gain is achieved with 15mm slot length with a reduction in operating range of iris. Slot voltage justifies the operating bandwidth of iris perturbation condition.
