In this paper, a compact-transmission-line (TL) decoupling and matching network (DMN) for three-element circular arrays is presented. As result of the miniaturization wireless terminals, antenna spacing too close, leading to large couplings deteriorating system performance. The DMN consists an impedance transformation section star-shaped neutralization which eliminates between antennas while oc...

A new miniaturized dominant mode leaky-wave antenna is proposed. This antenna is a transmission line structure with radiating wavenumber increasing from negative to positive values, providing backward to forward scanning capability as frequency is increased. The antenna profile is designed based on microstrip technology using balanced composite right left handed transmission lines (CRLH TL) app...

The ITER ECH Transmission Lines (TLs) are 63.5 mm diameter corrugated waveguides that will each carry 1 MW of power at 170 GHz with a transmission efficiency that should exceed 83%. The losses on the ITER TL have been calculated for four possible cases corresponding to having HE11 mode purity at the input of the TL of 100%, 97%, 90% and 80%. The losses due to coupling, Ohmic and mode conversion...

This article proposes an alternative method to compute the currents and voltages along overhead transmission lines (TL) represented by lumped model using a cascade of p-circuits, considering frequency effect on longitudinal parameters line. The simplifies formation state matrices reducing their dimensions, without affecting performance simulations. was used electromagnetic transients resulting ...

GHOSH, RAHUL. Error analysis of Through Reflect Line method for calibrating microwave measurements. (Under the direction of Professor Michael B. Steer) Uncertainty in transmission line based calibration techniques for microwave measurements are studied with the aim of identifying the optimum calibration conditions. Variation in the determined error parameters under certain conditions in Through...

Real-time estimation of transmission line (TL) parameters is essential for proper management and distribution networks. These can be used to detect incipient faults within the hence avoid any potential consequences. While some attempts found in literature estimate TL parameters, presented techniques are either complex or impractical. Moreover, none published so far implemented real time. This p...

A three-channel transmission line (TL) impedance model is proposed to address the charge transport behavior of molecular functionalized mesoscopic oxide electrodes at different bias conditions. A full general solution of the three-channel TL for the system is provided in this paper. Selected experimental results of impedance spectroscopy of mesoscopic Al2O3 and TiO2 networks, covered with a mon...

A novel structure of dual-composite right/left-handed transmission line (D-CRLH-TL) is proposed in this paper, and its electromagnetic characteristics are investigated in theory and simulation. The dispersion curve of the proposed structure has been derived by using Bloch-Floquet theory. The structure is composed with an “H”-shaped defected ground structure (DGS) and two stubs with rectangular ...

Parasitic worms (helminths) frequently have complex life cycles in which they are transmitted trophically between two or more successive hosts. Sexual reproduction often takes place in high trophic-level (TL) vertebrates, where parasites can grow to large sizes with high fecundity. Direct infection of high TL hosts, while advantageous, may be unachievable for parasites constrained to transmit t...
