Abstract
A resonant radar reflector assembly comprising first and second reflector members (A,B), the first and second and reflector members each being configured to resonate at their respective resonant frequency when irradiated by radio frequency (RF) radiation of a corresponding frequency, wherein the first member has a portion (A) responsive to an electric field applied parallel to an electric polarization axis of the first member, the second member having a corresponding portion (B) responsive to an electric field applied parallel to a corresponding electric polarization axis of the second member, the first member also having a portion (A) responsive to a magnetic field applied parallel to a magnetic polarization axis of the first member, the second member having a corresponding portion (B) responsive to a magnetic field applied parallel to a corresponding magnetic polarization axis of the second member, the first and second members being arranged such that at least one electric or magnetic polarization axis of the first member is substantially not parallel to the corresponding electric or magnetic polarization axis of the second member.
