Key Takeaways

- Microwave engineering involves the study of microwave components and their mathematical analysis.
- There are three types of modes in microwave engineering: TE, TM, and TEM modes. These modes are solutions of Maxwell's equations applied to specific devices.
- Each mode has its properties, including solutions, cut-off frequencies, and dominant modes.
- Impedance in microwave engineering can be intrinsic or electromagnetic. Intrinsic impedance depends on the material properties, while electromagnetic impedance is the ratio of the electric to the magnetic field.
- Devices commonly used in microwave engineering include the microstrip line. These devices are designed to produce an impedance matching.
