Integrated development environments have provided increasingly powerful tools for software creation, and yet the creation of complex computer programs remains difficult and time-consuming. Liveness in a programming environment has been identified as one direction in which to pursue further improvements in programmer productivity. We propose a scheme for achieving strategically predictive liveness, t

A wideband metasurfaced (MS) slot antenna is proposed for circularly polarized (CP) operation. The antenna consists of a crossed slot antenna (CSA) and a MS placed at a short distance above the CSA. The CSA has two slots placed in orthogonal positions and with distributed elements to generate two E-fields with 90°-phase difference for CP radiation. A microstrip line is used to single feed the CSA

This letter presents a wideband cross-slot antenna (CSA) with inductor loadings for dual polarization. The effects of the ground size on the impedance are investigated. To achieve a compact size, a very small ground having the same hypotenuse length as the slot is used. The inductor loadings are used at both ends of the slot to reduce the size further. Simulated results show that the loaded induct

In this paper, a novel generalized transition matrix (GTM) algorithm is proposed to analyze the electromagnetic problems of open-ended cavity structures. An artificial reference surface is applied to seal the slots and/or apertures to reshape the target cavity into an interior domain (containing inner metallic surface and internal structures) and an exterior domain (containing the outer surface of

Understanding the European Union - where it has its roots and how it works - is not the easiest thing. Nevertheless, it is an absolutely necessary knowledge to acquire in order as an individual to be able to navigate in today's Europe.

This chapter analyses how secondhand consumption and vintage fashion retailers are incorporated into Swedish urban life and the retail planning context. The chapter is part of an ongoing research project, studying retail planning and vintage fashion consumption practices. Key concepts when discussing retail and localization are attractiveness and accessibility. Cities are often characterised by th

An efficient algorithm based on the contour integral method (CIM) is presented in this letter for the modeling of lossy multiconductor transmission lines. Different from the volume integral equation, the CIM only discretizes the contour of the cross section of each conductor, which significantly reduces the number of unknowns in the resultant system equations. The solution of the CIM is accelerate

This paper presents a numerical method to evaluate the electromagnetic radiating characteristics of a large-scale phased antenna array by using generalized transition matrix modules. Choosing an appropriate reference surface to contain an antenna element, an associated generalized transition matrix (GTM) is defined to establish the relationships between the rotated tangential components of inciden

Construction of synthetic basis functions (SBFs) for analyzing the radiation problems of antenna arrays is discussed. The SBFs of a block are generated from two separate solution spaces, with one space to account for the effect of the feeding voltages, and the other space to account for the responses of the block to incident electromagnetic fields from its environment. Singular value decomposition
