I would like to thank my mentor and collaborators: Derek Kubo, Pablo Altamirano, Peter Oshiro, and John Chen.

Everyone at AMiBA and SMA for the use of facilities, materials and tools.

The rest of the Akamai interns for support, help, and friendship.Lastly Sarah Anderson, Lynne Raschke, Lisa Hunter, Hilary

O’Bryan, Scott Seagroves, as well as the entire CfAOMahalo to everyone!
