A novel compact ultra wideband (UWB) bandpass filter (BPF) based on composite right/left handed transmission line (CRLH TL) is reported in this paper. The proposed UWB BPF is designed and developed by coupling of two unit-cells of via-less CRLH TL, excited by asymmetrical coplanar waveguide (CPW) feed-line. The unit cell of CRLH TL is designed using series interdigital capacitor (IDC) in shunt ...

The climatological large-scale patterns of diurnal and semidiurnal near-surface wind variations over the tropical Pacific Ocean are documented using 3 yr of hourly measurements from the Tropical Atmosphere–Ocean moored buoy array. Semidiurnal variations account for 68% of the mean daily variance of the zonal wind component, while diurnal variations account for 82% of the mean daily variance of ...

This paper presents a novel approach for the design of microwave circuits using Adaptive Network Fuzzy Inference Optimizer (ANFIO). The method takes advantage of direct synthesis of subsections of the amplifier using very fast and accurate ANFIO models based on exact simulations using ADS. A mapping from course space to fine space known as space mapping is also used. The proposed synthesis appr...

This paper presents research on a low power CMOS UWB LNA based on a cascoded common source and current-reused topology. A systematic approach for the design procedure from narrow band to UWB is developed and discussed in detail. The power reduction can be achieved by using body biased technique and current-reused topology. The optimum width of the major transistor device M1 is determined by the...

In this study, a mechanical movable device is used to achieve tuning phase shifter with adjustable substrate, which has huge potentiality of range. The main body microstrip structure. substrate two layers one layer. By moving the layer, equivalent relative permittivity component changed and tunability realized. -128.2° 96.1° at 6GHz while transmission coefficient S21 from -2.09dB -2.70dB throug...

I report a theoretical study of collective coherent quantum-mechanical oscillations in disordered superconducting quantum metamaterials (SQMs), i.e. artificial arrays of interacting qubits (twolevels system). An unavoidable disorder in qubits parameters results in a substantial spread of qubits frequencies, and in the absence of electromagnetic interaction between qubits these individual quantu...

A graph is called integral if all its eigenvalues (of the adjacency matrix) are integers. In this paper, the graphs S1(t) = K1,t, S2(n, t), S3(m,n, t), S4(m,n, p, q), S5(m,n), S6(m,n, t), S8(m,n), S9(m,n, p, q), S10(n), S13(m,n), S17(m,n, p, q), S18(n, p, q, t), S19(m,n, p, t), S20(n, p, q) and S21(m, t) are defined. We construct the fifteen classes of larger graphs from the known 15 smaller in...

Osterloh, Kurt, Peter Gaehtgens, and Axel R. Pries. Determination of microvascular flow pattern formation in vivo. Am J Physiol Heart Circ Physiol 278: H1142–H1152, 2000.—Blood flow in microvessels differs significantly from that of red blood cells (RBC) flowing through long, straight glass tubes in vitro. The in vivo situation is characterized by the presence of plasma favoring aggregation, by...
