NEW WILKINSON POWER DIVIDERS BASED ON COMPACT STEPPED-IMPEDANCE TRANSMISSION LINES AND SHUNT OPEN STUBS [PDF]
Progress In Electromagnetics Research, 2012 This study presents new Wilkinson power dividers using compact stepped-impedance structures and capacitive loads to achieve the required power splitting. This approach can produce additional transmission zeros and efiectively suppress the desired stopbands because shunt open stubs realize capacitive loads.

Reflection of an acoustic line source by an impedance surface with uniform flow
, 2014 An exact analytic solution is derived for the 2D acoustic pressure field generated by a time-harmonic line mass source located above an impedance surface with uniform grazing flow. Closed-form asymptotic solutions in the far-field are also provided.

High impedance fault modeling and location for transmission line✰ [PDF]
, 2023 A fault in a power system generates economic losses, security problems, social problems and can even take human lives. Therefore, it is necessary to have an efficient fault location strategy to reduce the exposure time and recurrence of the fault.

Interpolation-Free Hybrid Bergeron–π Line Model with Accurate Zero-Sequence Impedance
EnergiesFixed-step real-time electromagnetic-transient (EMT) simulation of large power networks typically relies on parallel partitioning, where transmission-line elements serve as step-synchronous decoupling boundaries between subsystems.

Radioelectronic and Computer Systems, 2023 The subject matter of the article is the analysis and design of a via free metamaterial antenna based on a composite right/left-handed transmission line (CRLH-TL) structure. The goal is to design a high-gain antenna with dual-band resonance capable of changing its resonance frequency and gain adaptively.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

On the design of magnetically insulated transmission lines for z-pinch loads
Matter and Radiation at Extremes, 2019 Many papers have been published on the theory of magnetic insulation and the use of Zflow analysis of magnetically insulated transmission lines (MITLs). We describe herein a novel design process using the circuit code SCREAMER for a real-world MITL for z-
