A new reflecting surface capable of simulating identical reflecting properties of a metallic plate with rectangular corrugations is reported. The new surface which is fabricated with a low loss dielectric plate of uniform thickness .One surface of the plate is periodically loaded with a grill structure of conducting wires and the other surface is completely metalized with copper. Depending on t...

Indian borage/ Karpurvalli (Coleus aromaticus) is an herb with aromatic leaves with ajwain like flavour known for stimulating properties. The paper deals with the development of a shelf stable ready-to-reconstitute appetizer soup mix, convenient to the consumer. The central composite design with two ingredient variables i.e. karpurvalli leaves powder & green gram flour resulted in 13 experiment...

Printing functional materials represents a considerable impact on the access to manufacturing technology. In this paper we present a methodology and validation of print-and-self-fold miniature electric devices. Polyvinyl chloride laminated sheets based on metalized polyester film show reliable self-folding processes under a heat application, and it configures 3D electric devices. We exemplify t...

A metal-less RXI collimator has been designed using the Simultaneous multiple surface method (SMS). Unlike conventional RXI collimators, whose back surface and parts of the front surface have to be metalized, this collimator is completely metal-free, made only of plastic (PMMA). The collimator’s back surface is designed as a grooved surface providing two TIR reflections for all rays impinging o...

This paper presents a technique for the efficient and accurate determination of resonant frequencies and quality factors of Substrate Integrated Waveguide (SIW) resonators. To consider resonators of a general shape the SIW structure is modelled as a parallel plate waveguide populated with metalized via holes. The field into the SIW cavity is found by solving the scattering problem for the set o...

Wire bonding is a process that is used to form solid-state bonds to interconnect metals such as gold wires to metalized pads deposited on silicon integrated circuits. Typically, there are 3 main wire bonding techniques; Thermo-compression, Ultrasonic and Thermosonic. This experiment utilizes thermosonic bonding which applies heat, ultrasonic energy and force on an Au-Al system. Sixteen groups o...

The shelf-life of the product need to be evaluated according commercialization product. Shelf-life assessment can done using acceleration method (Accelerated Testing) with critical moisture content approach. This research used predict expired date energy bar based banana. required data such as initial water content, solid weight product, surface area packaging, permeability vapor saturated pres...

The design of a compact and wideband circularly polarized (CP) Monopulse antenna is presented. Firstly, the small-sized element (13mm $\times13$ mm), with impedance bandwidth (BW) 80.5% (4.3-10.1 GHz) axial ratio (AR) 48.1% (6-9.8 GHz...
