Note to moderator: Read answerline carefully. This process for ultrasound waves in soft tissue can be modeled with the time-fractional Szabo (“SAH-boh”) wave equation, which gives a power-law model of this process. Circuits named for this process include pi pads and T pads, which are named for the shapes in which resistors are connected. A metric for communication link performance is the ratio of this process to crosstalk. This process’s coefficient does not depend on frequency if a transmission line is distortionless. The strength of this quantity equals 10 times the log of [read slowly] “input intensity over output intensity.” This process corresponds to a negative value in decibels, so it is the opposite of amplification. If the refractive index is complex, the imaginary part describes this process. For 10 points, beam splitters act as devices named for what process, which reduces the intensity of lasers? ■END■
ANSWER: attenuation [or word forms such as attenuates or attenuating; accept acoustic attenuation or signal attenuation; accept attenuators or attenuator circuits; accept attenuation-to-crosstalk ratio; accept attenuation coefficient; accept extinction or extinction coefficient; accept signal loss; prompt on absorption or absorbing or absorbs until “absorption” is read; prompt on energy loss; prompt on dissipation by asking “what name is given to dissipation when energy is not lost as heat?”; prompt on damping by asking “damping is a more specific form of what process?”]
