EBG Structure Using Bridge Line in the Signal Transmission Plane

Changes in signal transmission speed in coaxial cables through regulating the foam structure of the polyethylene dielectric section

Polyolefins have been widely used in the electrical insulation and cable industry in recent years. One of the main usages of these materials is dielectric insulation in coaxial cables. Low attenuation and high signal transmission speed are among the desired features in coaxial cables. The role of polyethylene foam on signal transmission speed in the coaxial cables is the main focus of this stud...

Noise Suppression and Isolation in Mixed-signal Systems Using Alternating Impedance Electromagnetic Bandgap (ai-ebg) Structure

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Subterahertz signal crosstalk in transmission line interconnects

A low-temperature electro-optic sampling system was implemented to study the crosstalk of picosecond pulses between on-chip microstrip interconnects. With a submillivolt sensitivity and a subpicosecond temporal response, this system has allowed noninvasive, nodal testing of superconducting Nb integrated circuits. We have characterized pulse propagation and the crosstalk arising from two microst...

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
