Any meshless research here?

Dear all,

Is there any people research on the electromagnetic simulation by meshless or meshfree method? I am trying to study this method, could anyone discuss the advantages of this method, comparing to the traditional methods (FEM, MOM, BEM, FDTD, and so on), the classical articles and books about this, and any free source code to help me to study this method faster?


Thanks,
Zhanghong Tang
