RLC Circuit Model for the Scattering of Light by Small Negative Refractive Index Spheres

We study the scattering properties of very small spheres made of a negative refractive index (NRI) using circuit network principles. The Lorenz-Mie theory is used to represent the transverse magnetic and transverse electric scattering coefficients based on resistor, inductor, and capacitor (RLC) lad...

Zusammenfassung:We study the scattering properties of very small spheres made of a negative refractive index (NRI) using circuit network principles. The Lorenz-Mie theory is used to represent the transverse magnetic and transverse electric scattering coefficients based on resistor, inductor, and capacitor (RLC) ladder circuit models derived from continued fractions. The lumped elements are then analyzed and a comparison is made between these new elements and those expected for conventional positive refractive index spheres. This provides an alternative interpretation for the fact that the scattering efficiency Q sca for NRI spheres with size parameters x
