Negative Material Inspired Microwave Water Heating System

Abstract

Microwave heating is considered as a very beneficial heating methodology for liquids because it can provide non-contact delivery of energy. Recent studies are focusing on the use of an electrically small resonator, such as a split-ring resonator for liquid heating purposes for its ability to concentrate electric energy in its gap which can be translated into heating. The thesis proposes a novel and effective microwave water heating system based on split-ring resonators which cultivates a completely innovative approach resulting in more energy efficient outcomes. The thesis also provides a clear and step-by-step manual for conducting numerical analysis for microwave heating carried out by using multiple software tools, which can save valuable time for future researchers. The major section of the thesis presents the structure, dimensions and heating performance of the proposed heating elements, and different comparisons have been carried out for characteristic and performance realization of the heaters. The system provides very promising heating results numerically, such as for an input power of only 2 watts the system heats water up to 41 °C from room temperature in 60 seconds. These results establish that along with eliminating the shortcomings faced by currently employed household water heating systems, the proposed model is destined to be a promising and more energy efficient solution for meeting household water heating demand in future years.
