How to using master/slaver B.C. to model triangular array?

can we superimpose PML and M/S boundaries and do infinte phased array simulations...any examples of phasex array simulation using vivaldi antenna

Hello,

Can I know, why triangular lattice only useful when you have large periodic (a>>Lambda)?

thanks a lot for the reply

ur instructions are very hepful,but i still have a question . How did u split one face into two and then assign M/S boundary 2,3 respectively ,
