Standing Waves in Transmission Lines: Standing Waves in Transmission Lines : When power is applied to a transmission line by a generator, a voltage and a current appear whose values…
Standing Wave Ratio Measurements: Standing wave are created along the length of a transmission line due to the mismatch between the characteristic impedance Z0 and the terminating impedance of the…
Light Wave Spectrum: Light Wave Spectrum - In everyday terms, light can be defined as the pail of the visible spectrum that has a wavelength range between 0.4 μm (micrometer)…
Sawtooth Waveform in Beam Scanning: As previously discussed, one complete frame of a TV picture is scanned 30 times per second, in a manner very similar to reading this page.…
Surface Acoustic Waves Devices(SAW): Surface Acoustic Waves Devices may be propagated on the surfaces of solid piezoelectric materials, at frequencies in the VHF and UHF regions. Devices employing SAW principles…
Resonators and Waveguides Articles: 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…
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…
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…
