C l c3 Abstract-In this paper, a design method is described for low-sensitivity narrow-band band-pass switched-capacitor filters (SCF's) using a pseudo-2-path principle and a capacitor-error-free voltage inversion. The proposed method is based on the low-pass to high-pass transformation using voltage inversion, the pseudo2-path principle, the capacitance-ratio reduction technique and a very low...

* The authors are with the IMTEL Institute, Belgrade, Serbia and Montenegro Abstract – This paper presents a new concept of band-pass filters with capacitive coupled resonators applied for realization of a printed filter in L band. The significant size reduction achieved by the original construction allows filter realization at these very low microwave frequencies. The agreement between the pre...

This paper presents a single-element microstrip spade-shaped patch antennas with partial ground plane, integrated an electromagnetic band-gap (EBG) structure, and fed feedline to achieve wideband, dual-band band-notched characteristic. Two similar mushroom-like EBG structures built into the wideband antenna were used suppress specific band, resulting in dual-band. The wide-band achieved broad b...

Abstract: In this study, using density functional theory and the SIESTA computationalcode, we investigate the electronic and optical properties of the armchair graphenenanoribbons and the armchair boron nitride nanoribbons of width 25 in the presence of atransverse external electric field. We have observed that in the absence of the electricfield, these structures are se...

ZnO and ZnO: Mn nanocrystals synthesized via reverse micelle method. The structural properties nanocrystals were investigated by XRD and Transmission electron microscopy (TEM). The XRD results indicate that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. The various optical properties of these nanocrystals such as optical band gap energy, refractive index, dielectr...
