“…ffiffiffiffi ffi e R p 11 2 (11) Here Du is the phase required to be corrected, c53310 10 cm=s, x is frequency in radians, e R , is the relative permittivity and distance represents the length of brain and tumor mediums. Table 3 depicts the scale by which the brain and tumor permittivity changes to produce the same phase per subcarrier as our original CST Model, while Figure 8 illustrates the resultant difference in phases for the two models.…”

“…Mathematically, it requires SAR optimization to meet this challenge. Several techniques have been reported in recent research regarding SAR optimization in EM hyperthermia systems, including beamforming, time reversal, fixed‐time topology, inverse multiphysics strategy, genetic algorithms, eigenvalue‐based optimization, projection algorithm, and particle swarm optimization . When compared with EM fields, acoustic energy propagates with reduced speed and shorter wavelength values can be useful to target small‐sized tumors with deep penetration.…”

“…Thus, a robust and computationally efficient algorithm is needed to address the complexity of such systems. Various techniques have been reported in the literature for SAR optimization in EM hyperthermia systems such time reversal [ 50 ], fixed-time topology [ 51 ], inverse multiphysics strategy [ 52 ], genetic algorithms in [ 13 , 14 , 53 ], eigenvalue based optimization in [ 12 ], projection algorithm in [ 54 ], and particle swarm optimization in [ 55 ]. We devise an optimization technique based on the genetic algorithm to reduce any possible hotspots.…”

“…Karaciğer tümörü tedavisi için mikrodalga yayan bir antenin kullanımı ilk olarak 1979'da Tabuse tarafından önerildi ve 1985 yılında klinik uygulaması yapıldı (Tabuse, 1979;Tabuse ve ark., 1985). Mikrodalga antenlerinin çoğu ince, iğne benzeri koaksiyel tabanlı cihazlardır ve en popüler olanları monopol, dipol veya slot antenlerdir (Sharma, 2016). Mikrodalga ablasyonun karaciğer tümörleri yanında böbrek ve akciğerdeki çalışmaları da mevcuttur (He ve ark., 2004;Andreano ve ark., 2010;Brace, 2009;Vogl ve ark., 2011).…”
