The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

This thesis derives closed form equations to describe electromagnetic device characteristics for a toroid, solenoid and a case study induction machine. By considering stored magnetic field energy, this approach allows the relationship between electrical, magnetic and kinetic energy to be quantified and analyzed in ways that allows improved accuracy compared with conventional magnetic circuit modeling methods. This thesis also provides insights into how geometric parameters impact energy transfer and operational characteristics of electromagnetic devices.

Leachate is a noticeable pollution problem because it contains a considerable amount of persistent organic pollutants (POPs). If leachate isn't treated thoroughly, its leak will negatively affect the environment. Therefore, appropriate treatment technologies are required to remove them. Bio-Electro-Fenton (BEF) is a new method using microorganisms such as electrolytes to convert chemical energy into electricity to help create H2O2 support advanced oxidation process (AOPs).
