M orPho Rhetenor butterfly stealth technique radar cross section electromagnetic scattering finite difference time domain method
The electrom agnetic ( EM ) scattering of MorPho Rhetenor butterfly is investigated. A simplifiedmodel is obtained and the associated electromagnetic scattering incident by TE mode or TM mode is analyzed w ith finite difference time domain ( FDTD) method combined w ith extensive surface technique. Prospective scattering characteristics are verified. The scattering perform ance of the structure possesses not only the structural stealth but also the material stealth strongpoin.t The result shows that the research on the scattering of butterfly w ing benefits to the development of the stealth technique in China.
