Özet

For most cases, the reflection phase diagram of a curved High Impedance Surface (HIS) is independent of the curvature. However, the surface waves generated on HISs, due to their periodic geometry, distorts their reflection characteristics within specific frequency intervals. In those intervals, the reflection phase changes as a function of radius of curvature and size of the HIS. These effects are not observed for the flat cases because of the lower radiation resistance of the surface waves.
