Scattering of linearly polarized microwave radiation from a dielectric helix.
A method for calculating the electric field scattered from a helical dielectric target is compared to an equivalent experiment. The wavelength of the incident light is 3.18 cm, and the right-handed helix has a radius of 1.83 cm and wire radius of 0.24 cm, a pitch of 0.553 cm, and seven turns. The index of refraction of, the target is 1.626-i 0.012. A brief description of the Shifrin theory generalized to this application is given along with a discussion of the experiment, and the experimental intensities are compared to the first-order theory.
