Recent cloud computing communication strongly requires an order of magnitude higher bandwidth. For example, the maximum rate prescribed for SerDes and Interlaken is 28Gbps. This trend can be observed in new enterprise servers or enterprise routers. Boards and cards for enterprise devices are often relatively large, e.g., 300mm × 500mm, with more than 60 layers. Fine pitch wiring of over 300mm length...
This paper presents the comparison of the features of three dissimilar feeding methods namely co-axial probe, microstrip line and co-planer feeding for a thermally stable resonator antenna (TSRA). First, nanoparticles have been developed by using proper synthesis process and then mixed in accordance with their temperature coefficients such as to achieve thermal stability. The Nicholson-Ross-Weir conversion...
We implement amorphous-Al2O3 as а thermally-conductive shield in metallo-dielectric nanolasers, and demonstrate an electrically pumped device. Joint consideration of various design parameters reveals that this design allows the laser to dissipate heat through its shield, aiding thermal management in nanoscale devices.
Telephone buried cable (BC) protection is an essential demand to perform successful wired telecommunication system against theft. Data logging from sensor and electronic communication system can monitor buried cable state to ensure exist of the buried cable to be protected. A number of parameters are associated with telephone buried cable, thus different types of sensors are required to measure the...
Blade servers are constantly moving towards higher data rates and smaller form factor resulting in complex routing choices to accommodate various chassis configurations. Flexible printed circuit (FPC) cables or flex cables serve as a good choice for interconnect medium in such densely configured server systems. In this paper, various challenges involved in designing a high speed serial link using...
In this work, an investigation into the performance of Hetero-Dielectric Dual-Material-Gate SOI Tunnel FET (HD-DMG SOI TFET) by varying the work functions of both tunnel and auxiliary gates and analysing its influence on the transfer characteristics and the threshold voltage is done. With a suitable combination of work functions of both the tunnel and auxiliary gates, steeper Id-Vg variations and...
This paper presents the preliminary design of a biomimetic printable hexapod robot driven by soft actuators. The robot mimics the insect's design with six legs and shows the capability of versatile locomotion on flat terrains by using alternating tripod gait. The soft and multiple degree-of-freedom (multi-DOF) actuators based on dielectric elastomer provide required motions of the robot with a simple...
Lung cancer or pulmonary cancer is one of a dangerous cancer threatening human life since a long time ago. Even though, a conventional surgery is widely accepted as a gold standard for this cancer treatment, however a new medical maneuver still be investigated to perform with this disease. In this paper, we trail a simulation of thermal ablation by using microwave energy at 2.45GHz, 30 Watts for 10...

The evolution of space charges in Polypropylene (PP) filled with synthetic and natural nanoclay after aging with −25 kV/mm DC field under 50 °C were investigated. Following certain periods of aging, the space charge was measured by the PEA technique. The PP materials, bases for the two types of Polymer nanocomposites, i.e. PP were loaded with synthetic and natural nanoclay. The unfilled PP contains...
Bruggeman dielectric mixture expression is one of the widely used methods to characterize properties of heterogeneous materials. In this contribution, dielectric response of mixture systems generated with the Bruggeman effective mixture expression is studied to investigate the broadening of dielectric relaxation at various filler contents. The mixture is composed of two dielectric media. The studies...
In this paper, we report on a dielectric study of a series of composite systems based upon a polystyrene matrix (έm ∼2.7) containing dispersed particles of lead zirconate titanate (PZT) and barium titanate (BaTiO3) (in both cases, έp ∼1000). These components were chosen to give a high dielectric contrast within the system and, because polystyrene is readily etched using permanganic reagents, the size...
Materials with nonlinear conductivity is sometimes used as field grading materials in high voltage applications. With respect to this, the electrical conductive properties of composites containing polyaniline (PAni) and carbon black (CB) as electroactive fillers have been studied with respect to the filler/matrix ratio, type of matrix material and how the composites were processed. Flat pads were...
Not all dielectrics are perfect. The experimentalist would know how materials would react to an external excitation, and would record bulk conductivity values depending on their test setups and measurement system. To measure the correct bulk conductivity isothermal time domain measurement at room temperature could take long times and requires good current measurement and sometimes high voltage setups...
In this paper, a microwave dielectric sensor is presented using an open-ended microstrip line. It is fabricated in a standard 0.25 µm SiGe BiCMOS process (fT/fmax = 180/220 GHz). A theoretical basis of open-ended microstrip line as dielectric sensor has been proposed and it is used as a permittivity dependent capacitor in the Colpitts oscillator. The sensor distinguishes permittivities ranging from...
Higher transmit sensitivity and receive sensitivity at lower bias voltages would be achieved by CMUTs when their structure converges to an ideal parallel plate structure without an insulation layer. Using an insulation layer with high relative dielectric constant (high-K) helps achieving this goal with increased capacitance and large electric field in the vacuum gap. The effect of the insulation layer...
We show that scaling rules, quantum confinement in thin bodies, and the resulting gate leakage render imperative the use of low-dimensionality materials as channels in devices scaled beyond the 10 nm gate length. We then consider a few examples of two-dimensional materials of great interest, graphene and bilayer graphene, and show how the dielectric environment (gate and interlayer insulators, nearby...
The aim of this study is to investigate the impact of the variation of the physical and electrical parameters of a biphasic composite structure on the electromagnetic field transmission, reflection and absorption coefficients. These coefficients are the base for the evaluation of the shielding effectiveness of such materials. A systematic analysis is carried out and the relations between the composite...

The MOSFET device performance deteriorates when it is scaled down to 45nm node and an alternative device structure being studied. FinFETs are the alternative new device structure, which replaces the MOSFET. The comparative study of Double Gate MOSFET (DGMOSFET), Tri-gate Fin Field Effect Transistor (FinFET) and Gate All Around (GAA) FinFET structures has been done for 22nm and 16nm technologies. The...
