Each square ringh as a gap and is oppositely placed in the gap of the other ring. A size reduction is always possible in this kind of structure, but one should be careful about the set frequency. The described square type of metamaterial design is completely novel in the context of the head and hand with respect to the specific absorption-reduction rate (SAR). This design was used because more arrays can be placed within a given area. Mobile phones are relatively small, requiring small metamaterial designs. The finite-difference time-domain method with the lossy-Drude model is adopted in this analysis by using CST Microwave Studio. The technique of a SAR reduction is discussed, and the effects of the relating position, distance, and size of the square metamaterials on the SAR reduction were investigated. Using the square-type metamaterials, we have achieved a 53.03 % reduction of the initial SAR value for the case of 1 g SAR and a 68.08 % reduction for the case of 10 g SAR</dc:description><dc:description xml:lang="sl">V članku je prikazan razvoj resonatorja iz deljivih obročev (SRR), ki so sestavljeni iz dveh koncentričnih obročev kvadratnega prereza iz prevodnega materiala, ki kaže pomemben električni odziv pri mikrovalovni frekvenci. Oba kvadratna obroča imata režo in vsak obroč je nasprotno nameščen v reži drugega obroča. Zmanjšanje velikosti teh struktur je vedno mogoče, vendar pa je treba biti pozoren na načrtovano frekvenco. Trdimo, da je kvadratna oblika metamateriala popolnoma nov dizajn v okviru glave in roke za zmanjšanje stopnje absorpcije (SAR). Eden od pomembnih razlogov, zakaj je bila ta oblika uporabljena, je možnost več postavitev v danem področju. Mobilni telefoni so razmeroma majhni in zahtevajo majhne naprave iz metamaterialov. Domena končnih časovnih razlik z uporabo modela lossy-Drude je bila uporabljena v tej študiji uporabljajoč CST Microwave Studia. Prikazana je tehnika zmanjšanja SAR ter preiskovanih učinkov priloženih pozicij, razdalje in velikosti kvadratnega metamateriala na zmanjšanje SAR. S kvadratno obliko metamateriala je bilo doseženo 53,03-odstotno zmanjšanje začetne vrednosti SAR pri 1 g SAR in 68,08-odstotno zmanjšanje pri 10 g SAR</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-8R2I1ATJ"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-8R2I1ATJ" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-8R2I1ATJ/6a2dc7d8-6114-4352-83db-9ce07c2ec5df/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-8R2I1ATJ/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-8R2I1ATJ" /></ore:Aggregation></rdf:RDF>
