The superconductor is cooled below its critical temperature at a small constant electric field and this applied external voltage keeps the superconductor in normal state. In order to simulate the device, we use the formerly derived explicit analytical expressions for the conductivity of nanostructured superconductors supercooled below the critical temperature in electric field. Numerical analysis intended to alleviate the development of a device reveal that the negative differential conductivity region of the current-voltage characteristic leads to excitation of electric oscillations. This gives a hint that a hybrid device of nanostructured superconductors will work in terahertz frequencies. The study of layered high-Tc superconductors and electromagnetic waves emitted from them in space vacuum would be an important task for the future space technology.","PeriodicalId":233679,"journal":{"name":"TURKISH PHYSICAL SOCIETY 35TH INTERNATIONAL PHYSICS CONGRESS (TPS35)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116086295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most important applications of this module is medical images processing, visualization and calculation in radiotherapy.

For a homogeneously irradiated tumor with a dose, our simulator determines the TCP using acceptable real-simulations of a fractioned treatment, based on the tumor cell sensitivities of radiation, tumor volume, cell density and number of fractions.
