Latest Patents

Charmaine holds a patent for a Microwave/Optical Transformation Method. This invention presents a method to design and analyze distributed microwave circuit elements, which can be utilized to match impedance between these elements. Specifically, it can be applied in the design of filters and is particularly relevant for microwave stripline or microstrip equivalent elements. The method adapts an optical design tool known as the Optical Admittance Diagram (OAD) for the analysis and design of microwave circuits and components. It involves defining the physical microwave circuit in terms of equivalent components, transforming them into a continuous transmission line known as a microwave transformer circuit, and utilizing quarter wave segments. The design process includes transforming these segments into equivalent quarter wave optical thin film layers, which are then physically constructed using automatic photo-etching techniques and machining for fabrication.
