Time-dependent dielectric breakdown (TDDB) is becoming a critical reliability issue, since the electric field across dielectric increases as technology scales. Moreover, dielectric reliability is aggravated when interconnect spacings vary due to (vias and wires) mask misalignment. Although dielectric reliability can be mitigated by a larger interconnect pitch, such a guardband leads to signific...

Pureeing of sweetpotato (SP) is carried out to enhance the conversion of the roots into value-added products. During processing, production and home utilization, the puree is often heated (conventional cooking or microwaved), hence the need to measure the corresponding properties of SP puree. Thermal (specific heat, thermal conductivity, density, and thermal diffusivity) and dielectric properti...

We describe a microfluidic device with an integrated microwave heater specifically designed to dielectrically heat non-aqueous droplets using time-varying electrical fields with the frequency range between 700 and 900 MHz. The precise control of frequency, power, temperature and duration of the applied field opens up new vistas for experiments not attainable by conventional microwave heating. W...

This paper presents a miniaturized tunable bandpass filter, consisting of two coaxial dielectric resonators and a pair of parallel-coupled lines. A coaxial dielectric resonators and a microstrip line form a new step-impedance resonator (SIR), which is different from a conventional SIR. Varactor diodes are connected to SIRs to tune the center frequency. The gap between parallel-coupled lines con...

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

We propose an electrophoretic technique combining the use of a series of dielectric traps controlled by an ac electric field and conventional continuous field free-flow electrophoresis. From the theoretical model that we describe, one can expect, for DNA electrophoresis, an improvement of one to two orders of magnitude in the selectivities or experimental durations.
