antenna pattern calculation at the presence of objects

Dear All,

I'm interested in any useful sources/books-papers/code regarding the calculation of antenna patterns at the pressence of nearby obstacles (walls, metallic towers/objects etc). I'm interested in first principles on how to approach the topic. Any help or pointing to the right direction would be greatly appreciated.

Best regards,
Cross

You might want to check out what FEKO website has to say on the topic.

They've got some nice information on they're take on:
Antenna placement,
MLFMM,
PO,
UTD,
antenna design for placement on big structures.

u can use scattering priciple,,,see work by Mautz and harrington
