Role of reflective (metallic) support on microwave heating

Experimental study on the heating effects of microwave discharge caused by metals

“…[26][27][28] For instance, some theoretical investigations of microwave heating with/without metallic support or plate were done and it was found that various shapes of metallic support played important roles in optimizing heating effects. [26][27][28] For instance, some theoretical investigations of microwave heating with/without metallic support or plate were done and it was found that various shapes of metallic support played important roles in optimizing heating effects.…”

“…Some literatures have involved the metal-microwave interaction in microwave heating to some extent. [26][27][28] For instance, some theoretical investigations of microwave heating with/without metallic support or plate were done and it was found that various shapes of metallic support played important roles in optimizing heating effects. 26,[29][30][31] Hussain found that the interaction of microwaves with iron produced heat and the temperature rose to the range of 1100-1200 C and even up to the melting point of iron.…”

Generalized characterization of microwave power absorption for processing of circular shaped materials

“…The scenario becomes even more crucial for microwave therapy, where successful ablation of the target zone without damaging the surrounding tissues requires accurate knowledge of the detailed power absorption patterns. Accordingly, a series of target oriented research works has been conducted over the years, to identify the microwave heating dynamics within circular domains related to food processing (Basak, 2005, 2006, Basak, 2007a,b, Basak, 2011Ayappa, 2001, 2002;Gunasekaran and Yang, 2007;Knoerzer et al, 2008;Liu et al, 2013;Franca, 2000, 2002;Pandit and Prasad, 2003;Pitchai et al, 2012;Rakesh et al, 2010;Sakai et al, 2003Sakai et al, , 2004Samanta and Basak, 2009;Souraki et al, 2009;Zhou et al, 1995;Zhu et al, 2007), material processing (Chen et al, 2001(Chen et al, , 2011Kowalski and Pawlowski, 2011;Meier et al, 2009;Navarrete et al, 2012;Perry et al, 2002;Sangdao et al, 2006;Wang et al, 2009;Wu et al, 2004;Yasaka et al, 2006;Zhao et al, 2009), medical therapy (Brace et al, 2007;Li et al, 2012;Park et al, 2012;Stang et al, 2012;Tanaka et al, 1993;Yacoob and Hassan, 2012;Zastrow et al, 2011), etc. In spite of extensive research, a generalized material invariant analysis of the microwave power absorption characteristics within circular samples as a function of sample dimensions and material properties is yet to appear in the literature....…”
