Optik ve RF antenler arasinda kopru olusturma - RF kavite modeli ile optik yama anten tasarimi

Optical antennas are still in infancy as compared to their RF counterparts although they have been proposed and studied with variety of shapes and for variety of appli- cations. One would have expected that the maturity of RF antennas, both in design and analysis, would have had a more pronounced effect in the development of optical antennas. So far, optical antennas have only utilized the geometrical attributes of the RF antennas, but none of the analysis tools that provided a great deal of intuition to antenna engineers in the design of RF antennas. This study intends to narrow the gap by introducing an easy-to-understand and easy-to-implement analysis tool, commonly known as the cavity model, for RF patch antennas into the optical regime. Of course, due to some fundamental differences between RF and optical antennas, mapping the entirety of the cavity model and the functionality of patch antennas into optics may not be possible at all, or may require further studies. The importance of this approach is not because of its simplicity in understanding and implementation, rather its applicability to a broad class of patch antennas, such as rectangular, circular, triangular, etc., with a wealth of applications developed in RF, and more importantly its ability to provide intuition with which one can as- sess the outcome (radiation pattern, polarization, impedance matching, loading and tuning antenna properties, etc.) without going through complex trial-and-error simu- lation studies with no or very little intuitive guidance by the user. This study intends to open up a new gateway full of new design approaches, functionalities and intuitions in optical antennas.
