Abstract
An array of axially oriented thin resistive elements having a certain value of conductance or resistance in the axial direction is supported in dielectric material. For a wave at normal incidence, the apparatus is essentially invisible. For a wave incident at oblique angles in the E plane, current is induced in the resistive elements and dissipative attenuation occurs. The attenuation does not rely on resonance so that the apparatus operates over a wide frequency band and does not require tight dimensional tolerances.
