Abstract :
In this talk we will begin by reviewing the fundamentals of Metamaterials by asking the question: "How do we categorize metamaterials and derive their effective medium properties?" We will then go on to address a related question that is very relevant from the point of view of a practicing engineer, namely: "How can they help us build better \´widgets\´, such as flat superlenses, highly-directive small antennas, miniaturized sensors, cloaks that make objects invisible and devices that exhibit extraordinary transmission (EOT).
