The term "microwave" refers to electromagnetic radiation in the frequency range of approximately 300 MHz to 300 GHz, corresponding to wavelengths from one meter down to one millimeter. Unlike low-frequency signals, microwaves possess unique properties such as the ability to penetrate the ionosphere, reflection by metallic surfaces, and heating effects due to molecular resonance. These characteristics necessitate a specialized approach to circuit design and analysis.
Standard academic curricula, exemplifieded by the works of authors like Annapurna Das, emphasize that at these frequencies, the wavelength is comparable to the physical dimensions of the components. Consequently, conventional lumped-element circuit theory (based on Kirchhoff’s laws) becomes inadequate, and distributed circuit analysis or full-wave electromagnetic field theory must be employed.

Since you likely have a PDF on a screen, print out a large, blank Smith Chart. Das’s book has several at the back. You will need to physically draw circles and arcs to understand admittance and impedance transformation. You cannot learn this by scrolling.
