PROJECT TITLE :
Linear-to-Circular Polarization Reflector With Transmission Band
A brand new category of polarizing surface is proposed that during a given frequency band will replicate incident linearly polarized waves with circular polarization (CP) while at alternative frequencies is clear allowing incident waves to transmit unaffected. The proposed structure consists of two parallel anisotropic frequency selective surfaces (FSSs) that independently interact with TE or TM waves, respectively. The FSSs are designed to, respectively, transmit TE and TM waves among the identical transmission frequency vary, so that the combined structure is clear to all polarizations during this band. Likewise, the 2 arrays are designed to, respectively, reflect TE and TM incident waves during a common reflection band, thus that each one polarizations are totally reflected during this vary; if the separation of the 2 arrays is such that the TE and TM elements of an event wave polarized at slant forty five° expertise a 90° section shift, reflection will occur in CP. The concept and performance limitations are theoretically investigated using transmission line theory with full wave results. The expected performance is validated by means of experimental results on a fabricated prototype. The proposed structure is pertinent for employment as a quasi-optical diplexer in CP twin-band systems such as reflector antennas.
