High-frequency circuit continues to enjoy significant industrial attention, triggered by a host of radio-frequency (RF) and microwave (MW) products. It really is another branch different from the electrical engineering and computer science(Digital world) needed to be addressed concisely and effectively.
The book draws a clear connection between electrical engineering and physics by showing clearly how the lumped circuit abstraction directly derives from Maxwell's Equations and a set of simplifying assumptions. In fact. High-frequency circuit is at the in-between discipline.
It will be perfect if the RF Circuit is relevant in the future 2nd edition. That will give the students a whole/clear picture in the circuit field and well-understanding of the connection between circuit theory and the fundamental Maxwell's Equations.
