Curved spiral antennas for underwater biological applications

Abstract

I would like to extend my profound gratitude to Dr. James J. Niemeier for his mentorship and contribution to innumerable experiments and discussions on the different research projects that we worked on together. The IIHR Hydroscience and Engineering Laboratories staff, my fellow students and undergraduate research assistants for their help. Hannah Taylor for her help with initial prototypes of testing radio boards. Robert B. Hart (Gabriel) for his time as diver in the underwater experiments at the University of Iowa Aquatic Center diving pool. Jeffrey T. Schnell, high school intern, for his assistance with some of the initial experiments (Summer 2013) and 3-D modeling of cybermussel's backpack (Summer 2014). Matthew J. Janechek for his wonderful help in the 3-D curved spiral antenna modeling and 3-D printing of the antenna housing fixture. Michael J. Salino-Hugg for his assistance during the last stage of the research in testing the radioantenna system assemblage and underwater antenna measurements at the Wind Tunnel Annex Laboratory facilities water tank. Kathryn Temple for her assistance on the mussel shell material characterization related measurements. I express my gratitude to the following IIHR's shop staff for their collaboration in numerous tasks: Brandon Barquist, Christian Borgwardt, Nicholas T. Thornburg, Timothy J. Houser, among others.
