Transmission Path Design for Frequency-Specific Reflection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission path design techniques cannot effectively handle specified reflection values across different frequencies, as they are limited by uniquely determined characteristic impedance for suppressing reflections.
Innovation Solution
A system and method that include an acquisition unit for reflection specification values and a computation processing unit with reflection characteristic calculation, modification, and characteristic impedance distribution calculation units to iteratively adjust and correct the impedance distribution to meet specified reflection values and constraints, allowing for a transmission path design that accommodates varying reflection specifications across frequencies.

1Reliability
If a fixed characteristic impedance is used to suppress reflections, then reflection suppression is improved, but the ability to meet different reflection specifications across frequencies deteriorates
Solution Approach 1:
The patent applies dynamics by transforming the fixed characteristic impedance into a variable one that changes with frequency. The impedance distribution is made dynamic through frequency-dependent transformation ratios, allowing the system to adapt to different reflection specifications at different frequencies while maintaining effective reflection suppression across the entire frequency range.
