abstract = "The development and use of genetic programming (GP)
software to synthesise true-3D artificial magnetic
conductor (AMC) ground planes is presented, with the
focus on achieving a lower frequency response
(particularly in the high VHF to low UHF bands),
low-profile, broadband designs without the use of
absorbing or magnetic materials. Metallic 3D patterns
are embedded in one or more substrate layers with a PEC
bottom, and the patterning in the unit cell is allowed
to extend into neighbouring unit cells, thus achieving
a lower frequency response with much smaller unit cell
size and thickness. Four designs synthesized using the
developed GP software are presented with achieved
bandwidths ranging from 32.7percent to 71.1percent when
using the plus-minus 90 degrees reflection phase
criterion. Further, it is shown that through the use of
a parametric study, the centre frequency (0 angle
reflection phase) of one of the designs can be reduced
from 381.3 MHz to 87.8 MHz, which is a 77percent
reduction. The edge of the square unit cell size for
this miniaturised design is lambda_{0}/51 and the
thickness is lambda_{0}/61 at 83.9 MHz.",
