Transmission Line Parameters Extractor

Matlab implementation of patent Transmission-line simulators and methods (Patent# 8892414, Application# 12/713941).

Overview

Need to add:

Resonance treatment

Low-frequency conversion

Passivity check

Causality enforcement

s2rlgc_t.m: Extract TL RLGC params from S params
rlgc2s_t.m: Calculate S params from TL’s RLGC params
check_consistence.m: Accept the RLGC of the transmission line as input. Call rlgc2s_t.m to obtain the corresponding S parameters, and then call s2rlgc_t.m to re-extract RLGC. Comparing two sets of RLGC, they should be exactly the same.

test0.m: 500mil Single-line Transmission Line (Polar Si9000e)
test1.m: 500mil Coupled Transmission Line (Polar Si9000e)
1. test1_1.m: (good) Using larger frequency intervals
2. test1_2.m: (bad) Add randn noise to S, observe the impact on extracted-RLGC
3. test1_3.mlx: (Very bad) Try to clean outliers or smooth of RLGC.
  - 使用实时编辑器任务清理杂乱数据并找到极值
  - 数据平滑和离群值检测
test2.m: 200mil Four-line Transmission Line (Ansys 2020R1)
1. ~~test2_1.m~~: (deprecated) removing singular frequencies
2. ~~test2_2.m~~: (deprecated) 10mm, with freq range 10M ~ 70G, HFSS Automatically use casual materials enabled.
3. test2_3.m: HFSS_Welement -> ADS -> S
4. test2_4.mlx: (not good) Try to clean outliers or smooth of RLGC. (Ansys 2020R1)
test3.m: 200mil 16-line Transmission Line (Ansys 2020R1)
1. test3_1.m: HFSS_Welement -> ADS -> S
2. test3_2.mlx: (bad) Try to clean outliers or smooth of RLGC. (Ansys 2020R1)
