From 15 July 2025 to 18 July 2025, Prof. Ing. Owen Casha attended , the 11th International Conference on Control, Decision and 福利在线免费 Technologies, which was held in Split, Croatia. The conference was organised at the Radisson Blu Resort & Spa. Prof. Ing. Owen Casha, from the Department of Microelectronics and Nanoelectronics, presented a paper titled "Characterization of PCB Fabrication Processes for a Systematic and Efficient Design of Microstrip Circuits".
This paper proposes an algorithm to aid in the characterisation of a printed circuit board fabrication process before the design of microstrip circuits. By accurately characterising the electrical properties of a printed circuit board process, one can achieve a systematic and efficient design of microstrip circuits with reduced iteration cycles. The algorithm employs a mean-squared-error optimization technique while making use of de-embedded scattering parameter data from some sample microstrip transmission lines to estimate printed circuit board electrical parameters such as the tangent loss and the relative permittivity for a particular frequency range.
Prof. Ing. Casha also chaired one of the sessions held on 15 July 2025 titled "Cloud Computing and Wireless Communications".
