Several years ago I saw a television lecture about advances in domestic 
applicances. In that lecture, by someone from Thorn-EMI, a European brown 
and while goods manufacturer, said that an RF oven would be better than a 
microwave oven because it would really heat the food overall, and not just 
on a layer near the surface. He suggested that such products were in 
preparation.

However they never appeared. The reason may be that the technical 
difficulties over obeying regulations on radio frequency interference were 
insuperable. Although such equipment exists industrially, it is likely that 
a domestic version would be expensive to produce or it would be difficult to 
ensure that it was maintained so as to obey the regulations throughout its 
life.
