The optical and electrical properties of transparent conductive oxides (TCOs), traditionally used in thin-film silicon (TF-Si) solar cells as front-electrode materials, are interlinked, such that an increase in TCO transparency is generally achieved at the cost of reduced lateral conductance. Combining a highly transparent TCO front electrode of moderate conductance with metal fingers to suppor...

The idea that processes of second language acquisition (SLA) are highly relevant to an account of creole genesis is far from new or original (see Plag (2008a) for some discussion and further references). However, it is still controversial which kinds of SLA processes are relevant, and how much of a given creole’s structures can be attributed to such processes. In my previous three Columns (Plag...

This paper focused on the coaxial probe fed square patch microstrip antenna characteristics have been studied with and without dielectric Superstrates. The dielectric constant of the substrate and Superstrate material is used same for designing of square microstrip patch antenna. The antenna designed frequency is 2.4GHz(ISM band) using transmission line model. In this paper experimentally inves...

In this paper, a high gain, low side lobe level Fabry Perot Cavity antenna with feed patch array is proposed. The antenna structure consists of a microstrip antenna array, which is parasitically coupled with an array of square parasitic patches fabricated on a FR4 superstrate. The patches are fabricated at the bottom of superstrate and suspended in air with the help of dielectric rods at 0.5λ0 ...

A new metasurface superstrate structure (MSS)-loaded dual band microstrip line-fed small patch antenna is presented in this paper. The proposed antenna was designed on a ceramic-filled bioplastic sandwich substrate with a high dielectric constant. The proposed 7 × 6 element, square-shaped, single-sided MSS significantly improved the bandwidth and gain of the proposed antenna. The proposed MSS i...

There has been a lot of study published in literature on the improvement of the performances of microstrip patch antennas. Most of the solutions proposed in the past were to use an array of several antennas. The particular disadvantage of this method comes from the feeding of each antenna and also from the coupling between each element. Other interesting solutions have then been suggested: the ...

One of the central problems in creole studies is the nature of the processes that are involved in creolization. This paper investigates this issue with regard to the restructuring of the syllable in the genesis of one English-based creole, Sranan. In the emergence of Sranan, as in that of many other creoles, we can observe the restructuring of syllables through epenthesis and deletion of segmen...

3.1 INTRODUCTION This chapter explains the methods to improve the directivity, and bandwidth of microstrip antenna array, using EBG structures and the FSS as a superstrate layer. This chapter also details the concept, principles of operation and the geometries of the unit cell of various EBG structures used, along with the microstrip antenna array configuration. Using the Multiconductor Transmi...
