Abstract

A single thin conducting plane with an array of thin linear slots in free space is investigated. Using a finite-by-infinite array analysis, random errors are introduced in the slot geometries along the finite direction, while perfect periodicity is maintained in the infinite direction, allowing Floquet´s theorem to be used. Fields transmitted from an incident plane wave are examined in the principal plane, normal to the infinite axis. A study is made by varying the standard deviation of the geometric errors, to determine manufacturing tolerance requirements for maintaining peak transmission levels and for keeping sidelobes down.<>
