A planar compact bandstop filter (BSF) and a miniaturized resonator structure are presented along with its analytical equation to obtain resonance. The resonator is miniaturized by means of a shorted-stub which is loaded to a closed-loop resonator. Design and implementation of a 2.1 GHz BSF with 6% fractional bandwidth is presented.

In this paper an rectangular patch with parasitic stub whose edge have been cut , with two slots near the feedline has been proposed. The antenna is designed using HFSS software. The designed antenna shows wideband characteristics having simulated bandwidth of 96 %.The overall dimension of the antenna are 35×35×1.6 mm 3 .This antenna obtained maximum gain of 9.55dB having VSWR is less than 2. K...

• influences due to handling problems, distractions from environment or no unifying screen resolution. • participants might be used to TRA (a few trials of level 1 to 3 participants provide evidence) Future Work: • compare TRA layouts with layouts supporting 1/4SHPEDs [4] • with short “breaks" between serving graphs we may use the same graph in both models • investigate other stub sizes and mor...

We use the SSTL (Singwi, Sjölander, Tosi, Land) approximation to investigate the short–range correlations in a one dimensional electron gas, for the first time. Although SSTL is introduced to better satisfy the compressibility sum rule in three dimensions, we show that the widely used STLS (Singwi, Tosi, Land, Sjölander) approximation is more successful in the case of the one dimensional electr...

Feature interaction (FI, in short) is a functional conflict among multiple telecommunication services, which is never expected from services in isolation. Detecting all possible FIs is an expensive and even infeasible task, due to the combinatorial explosion in the number of service combinations and scenarios. To reduce the cost of FI detection, FI filtering is known as a low-cost process condu...

Novel lumped dual-frequency impedance transformers (DFITs) for arbitrary frequency dependent complex loads (FDCLs) are synthesized using the concepts of capacitive and inductive inverters. Such a dual-frequency impedance transformer is constructed with one Pi-shaped lumped inverter and two shunt susceptance blocks at two sides, and get simplified after susceptance merging. The shunt susceptance...

a 56-year-old man with a two year history of chronic stable angina underwent elective coronary artery bypass grafting (cabg) due to angiographic report of three vessel disease and tight stenosis at proximal part of left anterior descending artery (lad). while harvesting of radial artery (ra), the distal half of radial artery was found to bifurcate to two parallel branches with equal size. we us...

Edge bundling is a technique to reduce clutter by routing parts of several edges along a shared path. In particular, it is used for visualization of geographic networks where vertices have fixed coordinates. Two main drawbacks of the common approach of bundling the interior of edges are that (i) tangents at endpoints deviate from the line connecting the two endpoints in an uncontrolled way and ...

We have studied the quantum transmission properties of serial stub and loop structures. Throughout we have considered free electron networks and the scattering arises solely due to the geometric nature of the problem. The band formation in these geometric structures is analyzed and compared with the conventional periodic potential scatterers. Some essential differences are pointed out. We show ...
