Various mixer design schemes are proposed to reduce the radar cross-section (RCS) of the aircraft and suppress the infrared signal. The infrared radiation characteristics and electromagnetic scattering characteristics of the funnel mixer, the annular mixer, and the lobed mixer are comprehensively studied and analyzed, using iterative physical optics (IPO) method and inverse Monte Carlo method.
