As wireless devices become more prevalent, the radio frequency (RF) spectrum is becoming more densely populated with cell phone and internet related broadband activities (e.g. text messaging, web browsing, and wireless routing). This feasibility study presents a sensitivity study on how location, use of an antenna and motion may impact the ability to measure RF power density for specific frequencies. The RF power obtained from a nearby radio station was compared to the relative RF power available for frequencies understudy. The results of the study indicated that 2.4 GHz is significant in terms of prevalence and power density which allows for technological opportunity and caution due to potential health hazards. Optimization of a 2D inductor is also presented and which makes it easier for RF inductor designers to selectively choose the dimensions and number of turns of the inductor based on the desired inductance and power. === A Dissertation submitted to the Department of Industrial Engineering in partial fulfillment of the requirements for the degree of Doctor of Philosophy. === Summer Semester, 2007. === May 22, 2007. === RF, Radio Frequency, Inductor, Energy, Inductance, Harvesting, Power === Includes bibliographical references. === Yaw A.
