设计步骤
1. Draw the unit cell, containing all appropriate boundaries and source definitions.
2. Create the antenna array, including name, dimensions, master and slave boundaries where needed for conformal meshing, and selection of row and column master/slave pairs for implicit definition of lattice propagation vectors. Designate which cells are active, passive, and padding.
