The AMC structure consists of an array of interconnected cylinders. Unit cell simulation results are presented, as well as a validation of the reflection properties with a Hertzian Dipole (HD) placed on top of a 10-unit cells AMC. A comparison is made with an HD alone and with an HD on top of a Perfect Magnetic Conductor (PMC).enfalseconference paper
