By irradiating a spheroid by means of a plane wave, the relationship between the radiated electromagnetic fields and the internal fields generated in the object can be studied. The SAR could be calculated with conventional numerical methods up to 9 GHz with the computational power available. To overcome this limit, an approach using physical optics is proposed to extend the simulation range up to 100 GHz. Preliminary results obtained indicate that this could be a good alternative for high frequency simulations; however, the generalization of the method and further validation would be required as future work.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Este trabajo exploratorio discute la simulación de la tasa de absorción específica (SAR) de cuerpo completo sobre objetos eléctricamente grandes. Al irradiar un esferoide por medio de una onda plana se puede estudiar la relación entre los campos electromagnéticos irradiados y los campos internos generados en el objeto. Fue posible calcular el SAR de cuerpo completo a través de métodos numéricos convencionales hasta 9 GHz con la capacidad de procesamiento computacional disponible. Para superar ese límite, se propone un acercamiento por medio de óptica física con el cual se pudo extender el rango de las simulaciones hasta 100 GHz. Los resultados obtenidos indican que este puede ser un acercamiento adecuado para simulaciones en alta frecuencia, sin embargo, se requiere generalizar el método y validarlo de forma estricta como trabajo a futuro.]]></p></abstract>
