One of the topologies that can work at high Power and high Quality simultaneously is the DCI-NPC topology. This new topology has new parts and presents new voltage and distortion errors. One of these new elements are the MOSFET parasitic Diodes. These Parasitic-Diodes presents a Recovery Reverse Time (trr) and its distorting effects generates signal and quality losses, and EMI problems. These p...

Principle, control theory, and application of the ESPAR (Electrically Steerable Parasitic Array Radiator) antenna are introduced. A typical ESPAR antenna consists of monopole or dipole elements, one of which is the radiator (fed element) and the others are the parasitic radiators with variable reactance devices loaded on them. It can provide a lower-cost solution as an adaptive array antenna or...

Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein (CRISPR-Cas) systems store the memory of past encounters with foreign DNA in unique spacers that are inserted between direct repeats in CRISPR arrays. For only a small fraction of the spacers, homologous sequences, called protospacers, are detectable in viral, plasmid, and microbial genomes. The rest of the ...

When a patch is placed close to the fed patch, get excited due to parasitic coupling between the two elements. This proposed work presents theoretical analysis of rectangular gap coupled microstrip patch antenna (R-GCMSA) using circuit concept model, and the effect of gap(g), feed width(W f), and feed length on performance of the impedance bandwidth is also studied, it is observe as the gap bet...

Analysis of effects due to parasitics is of vital importance during the design of large-scale integrated circuits, since it gives insight into how circuit performance is affected by undesired parasitic effects. Due to the increasing amount of interconnect and metal layers, parasitic extraction and simulation may become very time consuming or even unfeasible. Developments are presented, for redu...

Modern communication demands a low-profile, versatile antenna. In this paper, low-profile antenna of size 38 × 40 0.787 m 3 is proposed to reconfigure frequency and radiation pattern. The Rogers RT Duroid 5870 dielectric con...

In this paper the Finite Element Method is employed for the analysis of electromagnetic lossless waveguides. The curl-curl equation, deduced from Maxwell equations, is solved for the electric eld. We have studied the appearance of parasitic solutions and formulated a suucient condition for their elimination which puts a contraint on the Finite Element spaces for the approximation of the eld com...
