OFF THE SHELf

摘要

A new technique accelerates the design of low-profile and zero-profile antennas installed in the earth. Reportedly reduces computer memory requirements and cuts simulation times from days to an hour or two. Previously, these antennae were modeled to at least three times the skin depth of the wave to allow space and time for the ground wave to be differentiated from the fields that propagate into the earth, which are ultimately dissipated in the dielectric losses.
