Fine‐tuning snowflake fractal antennas

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2017
AbstractWe present a simple yet effective approach for fine‐tuning operating frequencies of snowflake fractal antennas. Given a basic design, a set of numerical simulations involving alternative corner angles are carried out to compute their isolated effects on frequency bands.

Looking at Soil as It Is: Evolution of Microscopic Soil Characterization From Kubiëna to Artificial Intelligence

Journal of Plant Nutrition and Soil Science, EarlyView.
We provide a historic overview of microscopic soil structure characterization from its founding father, Walter Kubiëna, to several technical revolutions like automation, digitalization, and artificial intelligence. In addition to technical advancements, we explore how concepts and research questions have evolved in time.

A Sequential One‐Pot Block Copolymer Synthesis: Toward Mesoporous Carbon Materials for Selective CO2 Adsorption

Macromolecular Rapid Communications, EarlyView.
A sequential one‐pot photo‐iniferter RAFT method greatly simplifies the synthesis of PAN‐based block copolymers, offering quick access to hierarchically porous, N‐doped carbon membranes. This scalable and reliable process allows for easy fabrication of functional materials important for carbon capture applications.

Antenna systems based on chiral metamaterials with fractal radiator geometry for radio communication systems

Физика волновых процессов и радиотехнические системы
Background. In wireless mobile communications, there are often situations when several radio transmitting devices operate on a single antenna system in several frequency bands, and therefore there is a need to create efficient multi-frequency antenna ...

Mobilizing Presence across Borders: Devotion to Papua New Guinea's Blessed Peter To Rot in Australia

Oceania, EarlyView.
ABSTRACT This article engages with the conjunctures between migration and religion by focusing on the celebration of Papua New Guinea's ‘National Patron Saint’, the Blessed Peter To Rot, in the Australian diaspora. Both in Sydney and Brisbane, Catholic Papua New Guinea (PNG) migrants have been ‘relocating’ PNG shrines, regalia, relics and ritual ...

Fractal Antenna Applications

, 2010
Fractals are geometric shapes that repeat itself over a variety of scale sizes so the shape looks the same viewed at different scales. For such mathematical shapes B.Mandelbrot [1] introduced the term of “fractal curve”. Such a name is used to describe a family of geometrical objects that are not defined in standard Euclidean geometry.

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous
