Study on the long range active coated nano particles

The plane wave scattering from the cooperated active cylindrical coated nano-particle and inverse active cylindrical coated nano-particle were studied numerically. It was found that the maximum peak of the cooperated active cylindrical coated nano-particle and inverse active cylindrical coated nano-particle, -90.217dBsm, is much larger the value, -106.843dBsm, of active cylindrical coated nano-particle or -100.597dBsm of inverse active cylindrical coated nano-particle. And the whole length of cooperated active cylindrical coated nano-particle and inverse active cylindrical coated nano-particle is 64.43nm, which is larger than the single active cylindrical coated nano-particle or the single inverse active cylindrical coated nano-particle. This give us a method to realize long range active coated nano particles by alternating connection the AC-CNP and IAC-CNP extensively.
