Electric Field Signatures in Wideband, 3 MHz and 30 MHz of Negative Ground Flashes Pertinent to Swedish Thunderstorms

In this study, the electric field signatures of negative ground flashes pertinent to the Swedish thunderstorms were recorded simultaneously during the summer of 2014 using wide (up to 100 MHz) and narrow (at 3 MHz and 30 MHz as central frequencies) bandwidth antenna systems. The electric field signatures were recorded for a time duration of 250 ms. In the analysis, the whole flash was considere...

A 30-MHz Trellis Codec Chip for Partial-Response Channels

We present a rate 8/10 matched-spectral-null Write Channel (MSN) trellis codec chip which can increase noise tolerance in partial-response channels applicable to digital magnetic recording. The Viterbi detector in this codec features an area-efficient pipelined architecture and a modulo metric normalization technique. The chip was implemented in a 1.2-pm CMOS process with a die size of 22 mm’. ...

Compact 30:1 Bandwidth Ratio Balun for Printed Balanced Antennas

A new compact 30 : 1 bandwidth ratio balun and its application to balanced antennas are presented in this paper. To realize the balun-type function, two different types of wideband transition structures are adopted for unbalanced and balanced outputs of the balun. Further, a Vivaldi antenna integrated with the proposed balun is designed and fabricated to validate the feasibility of the new appr...

A Thinning Method of Linear And Planar Array Antennas To Reduce SLL of Radiation Pattern By GWO And ICA Algorithms

In the recent years, the optimization techniques using evolutionary algorithms have been widely used to solve electromagnetic problems. These algorithms use thinning the antenna arrays with the aim of reducing the complexity and thus achieving the optimal solution and decreasing the side lobe level. To obtain the optimal solution, thinning is performed by removing some elements in an array thro...

Phase-I monitoring of standard deviations in multistage linear profiles

In most modern manufacturing systems, products are often the output of some multistage processes. In these processes, the stages are dependent on each other, where the output quality of each stage depends also on the output quality of the previous stages. This property is called the cascade property. Although there are many studies in multistage process monitoring, there are fewer works on prof...
