Schematic view of a circular TI cylinder placed along the z axis.
The subscripts i and s denote incident and scattered waves, respectively. TE waves with a wave vector 
are incident perpendicularly to the TI cylinder, where 
. Another coordinate system is introduced to describe scattered waves in the far field with the orthonormal basis vectors: 
(ks is the wave vector along the wave normal of scattered waves and lies in the x-y plane); 
lies in the x-y plane but perpendicular to both 
and 
; and 
. Note that ks makes a scattering angle Ï• with the y axis. Both the electric and magnetic fields of scattered waves lie in the 
plane but may rotate by the same angle β due to the TME effect.
