Multiband bandpass filters (BPFs) and multiplexers are essential front-end modules in the development of multifunction, multistandard, multiband wireless communication, sensing, positioning systems that required current future intelligent electronics applications. In this paper, numerous implementation schemes topologies BPFs multiplexers, which have been proposed, studied, developed so far, ho...

Unconventional alternatives such as aerobic and anaerobic effluent from starch industry contain essential nutrients for Btk active ingredient synthesis. Effluent is rich in carbon nitrogen can replace expensive feedstock used during the fermentation process. The main objective of this study was to achieve a biopesticide formulation wastewater (SIW) with high entomotoxicity (UI/ml) larvae compar...

In this paper, a directional coupler is designed using the substrate integrated waveguide (SIW) method. The SIW consists of double-layer with transverse rectangular slots in middle two layers. proposed contains three ports. placement ports considered based on generalization power divider network. Each layer printed 0.508 mm Rogers RT/Duroid 5880 ( ε r = 2.2 $\epsilon _r=2.2$ and t n δ 0.0009 $t...

A bandpass negative group delay (NGD) passive circuit based on defect ground structure (DGS) and substrate integrated waveguide (SIW)-matched is developed in the paper. The NGD DGS topology originally built with notched cells associated self-matched elements. design method introduced as a function of geometrical SIW via Then, parametric analyses full wave 3-D electromagnetic <tex xmlns:mml="htt...

A novel strawberry-like organic-inorganic hybrid, {Na(H(2)O)(3)[Lu(pydc)(H(2)O)(3)](3)}[SiW(12)O(40)]·26.5H(2)O (H(2)pydc = pyridine-2,6-dicarboxylate) containing an intriguing trinuclear lutetium cluster {Na(H(2)O)(3)[Lu(pydc)(H(2)O)(3)](3)}(4+) has been synthesized and its luminescent properties, IR, UV, TG, PXRD analyses and single crystal X-ray diffraction were investigated.

Microwave resonators working as sensors can detect only a single analyte at a time. To address this issue, a TE20-mode substrate-integrated waveguide (SIW) resonator is exploited, owing to its two distinct regions of high-intensity electric fields, which can be manipulated by loading two chemicals. Two microfluidic channels with unequal fluid-carrying capacities, engraved in a polydimethylsilox...

The photocatalytic inactivation (PCI) of Escherichia coli (Gram-negative) and Bacillus subtilis (Gram-positive) was performed using polyoxometalate (POM) as a homogeneous photocatalyst and compared with that of heterogeneous TiO2 photocatalyst. Aqueous suspensions of the microorganisms (10(7)-10(8)cfu ml(-1)) and POM (or TiO2) were irradiated with black light lamps. The POM-PCI was faster than ...

This paper presents a comparison between innovative technique for implementation of substrate integrated waveguide band pass filter centered at 4 GHz and conventional PCB results . Two poles filter is designed, simulated and fabricated. The novel fabrication process technique is based on green manufacturing where physical etching of metal layer of aluminum is glued on paper substrate. The pass ...

In this article, a novel compact reconfigurable antenna based on substrate integrated waveguide (SIW) technology is introduced. The geometry of the proposed antennas is symmetric with respect to the horizontal center line. The electrical shape of the antenna is composed of double H-plane SIW based horn antennas and radio frequency micro electro mechanical system (RF-MEMS) actuators. The RF-MEMS...
