Rectangular Waveguide Derivation: When the top and bottom walls are added to our parallel-plane waveguide, the result is the standard Rectangular Waveguide Derivation used in practice. The two new walls do not really affect any of the results so far obtained and are not really needed in theory. In practice, their presence is required to […]

Parallel Plane Waveguide: Parallel Plane Waveguide – As we know already in connection with transmission lines, that reflections and standing waves are produced if a line is terminated in a short circuit, and that there is a voltage zero and a current maximum at this termination. This is illustrated again in Figure 10-8, because it

Reflection of Electromagnetic Waves by a Conducting Surface: In view of the way in which signals propagate in waveguides, it is now necessary to consider what happens to Reflection of Electromagnetic Waves when they encounter a conducting surface. An electromagnetic plane wave in space is transverse-electromagnetic, or TEM. The electric field, the magnetic field and

Rectangular Waveguides: Rectangular Waveguides – As we know already that the term skin effect indicated that the majority of the current flow (at very high frequencies) will occur mostly along the surface of the conductor and very little at the center. This phenomenon has led to the development of hollow, conductors known as waveguides. To
