“…This early analysis indicates the interest and also the concern of many lecturers on how to improve the knowledge, skills, and understanding of radar students. When comparing proposals at the time of the analysis [3], and more than a decade later [4,5], a short evolution could be observed: different authors published their ideas on teaching subjects related to radar and their methods are very similar. The three cited proposals are based on master classes on explaining the concepts and equations, helped by laboratory sessions complementing these classroom performances.…”

The information exchange has evolved from traditional books to computers and Internet in a few years' time. Our current university students were born in this age: they learn and have fun with different methods as previous generations did. These digital natives enjoy computer games. Thus, designing games for learning some selected topics could be a good teaching strategy for such collective and also for undergraduate university students. This paper describes the development and test of an educational computer game revolving around radar. The objective of the game RADAR Technology is to teach students about the fundamentals of radar, while having fun during the learning experience. Based on the principle that you learn better what you practice, the authors want to induce students to discover a difficult to understand topic by proposing them a different experience, in a format better adapted to their generation skills. The computer game has been tested with actual students and the obtained results seem to be very promising.

“…The physics of operation of a wave guide cavity based Gunn Oscillator (GO) has been studied at length during last fifty years since the invention of the Gunn diode in the early sixties of the last century [1][2][3][4][5][6]. A number of theoretical models for the GO have been proposed in the literature to explain the obtained experimental observations regarding the onset and the stabilization of oscillations in a GO [7][8][9].…”

Abstract-The dynamics of the onset of oscillations in a wave guide cavity based Gunn Oscillator (GO) has been critically examined through numerical simulations and experimental studies.The transition of the GO from a non-oscillatory to an oscillatory state and the same in the reverse direction occurs at different critical values of the dc bias voltage applied to the GO. In presence of a weak RF field in GO cavity, oscillations with broad band continuous spectrum and multiple discrete line spectrum are observed at the GO output for different values of dc bias below the above mentioned critical values. Analysing the numerically obtained time series data, chaos quantifiers have been obtained to prove the occurrence of the chaotic oscillations in the GO. Experimental results and observations of numerical simulation show good qualitative agreement.
