We celebrate many anniversaries this year. IEEE traces its roots back to 1884, so 2024 marks the 140th anniversary of the society [1] . This year also marks the 75th anniversary of the Antennas and Propagation Society. This column, which had its inception in 1987 when the Antennas and Propagation Magazine was still a Newsletter , has also been appearing (under the name Microwave Surfing) in the Microwave Magazine since its first issue came out in 2000, so we are in the 25th year of that publication! Therefore, I consider the quiz below a special anniversary edition. It is now time to grab a pen and take a crack at it! Google and ChatGPT are not allowed.

In modern wireless systems, it is essential to incorporate numerous functions into a single component to accomplish cost-effective, lossless, and miniaturized properties. To achieve these facilities, multifunctional devices (MFDs) are necessary. An MFD is an electromagnetic radiating or receiving device that offers additional functions that might comprise multiple bands, reconfiguration, filtering, and active devices. A frequency-reconfigurable radiating device is able to adjust its frequency of operation over a wide bandwidth, which reduces the need for multiple radiating devices for different wireless services. Hence, the price and the dimensions of the wireless system can be minimized.

ChatGBT. Copilot. Gemini. These and other artificial intelligence (AI) tools are in the news and help us complete tasks faster than ever. The press coverage on the future of AI technologies is ample and both positive and negative; however presented, though, these technologies are here to stay. These AI tools are a paradigm shift in the way we perform our day-to-day activities, and this includes their place in the publication space. I have had many conversations with colleagues over the last year where concern has been expressed about the impact AI tools will have on publications’ integrity.

Electromagnetics (EM)-based optimization techniques have always been a major interest in the microwave research community due to their vital role in the design and development of microwave circuits and systems. Achieving the desired specifications in terms of S-parameters over different frequency bands is one of the critical steps in the microwave circuit and system design and development process [1] . An optimal design can be accomplished by using an optimization algorithm. Such an optimizer is set to iteratively find the optimized design with respect to predefined specifications starting from an initial design stage by invoking an EM simulator each time for evaluating the design evolution and optimization feasibility. This iterative approach takes an exceptionally long time, as many EM simulations are generally required for different sets of combinatory geometrical parameters during the optimization process [2] .
基于电磁学（EM）的优化技术在微波电路和系统的设计与开发中发挥着至关重要的作用，因此一直是微波研究界的主要关注点。在不同频段上实现所需的 S 参数规格是微波电路和系统设计与开发过程中的关键步骤之一[1]。优化设计可通过使用优化算法来实现。这种优化器从初始设计阶段开始，每次都会调用电磁模拟器来评估设计的演变和优化的可行性，从而根据预定义的规格反复寻找优化设计。这种迭代方法耗时极长，因为在优化过程中，通常需要对不同的组合几何参数集进行多次电磁模拟[2]。

RF power amplifiers (PAs) serve an important role for various applications, such as communication, induction heating, plasma generation, and wireless power transfer [1] , [2] , [3] . With the current demands for energy conservation, the importance of high-efficiency PAs has been ever increasing. Efficient power delivery alleviates the burden of thermal management, improving the system stability and increasing the power density. In this article, we present our first-place design for the Student Design Competition “High-Efficiency Power Amplifier for 50 MHz” in the 2023 IEEE International Microwave Symposium (IMS) in San Diego, CA, USA.
