Transmission Lines

open access: yes, 2022
AbstractIn EMC, it is essential to understand the concept of transmission lines and when to apply it. Because once a signal interconnection line exceeds a critical length lcritical [m], impedance matching ( $$ \underline {Z}_{source}$$ Z

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Modal transformation applied to double three-phase transmission lines

open access: yes, 2004
Double three-phase transmission lines are analyzed in this paper using a modal transformation model. The main attribute of this model is the use of a single real transformation matrix based on line geometrical characteristics and the Clarke matrix ...

Miniaturized Quadrature Hybrid Couplers based on Novel U-shaped Transmission Lines [PDF]

open access: yes, 2019
In this paper, a miniaturized microstrip quadrature hybrid coupler (QHC) using U-shaped transmission lines (USTLs) is presented. The proposed approach replaces all arms of the conventional QHC with its equivalent USTL to achieve compactness. The proposed
