    Understanding Reflections and Standing Waves in RF Circuit

    High-frequency circuit design must account for two important though somewhat mysterious phenomena: reflections and standing waves. We know from our exposure to other branches of science that waves are associated with special types of behavior. Light waves refract when they move from one medium (such as air) into a different medium (such as glass).
