Abstract
High impedance surfaces are generally characterized by reflection coefficient measurements. Other methods such as surface wave suppression measurements are used but do not provide as useful information. For ideal lossless high impedance surfaces the reflection coefficient magnitude is one while the phase angle varies greatly with frequency. However, by placing a resistive sheet near the high impedance surface, the magnitude of the reflection coefficient can also be made to vary with frequency
