A non-contact system and heating method includes a blackbody core heated according to Molecular Resonant Wavelength-Radio Frequency Heating method. Radio frequency waves of a resonant frequency travel in a hollow channel of a waveguide that contains an object, such as a blackbody core. The core is structurally secured within the waveguide by a spring system that supports the base of the core, yet the core does not touch the waveguide and does not conduct heat to the waveguide. The core absorbs the RF energy and generates heat by molecular friction within the material of the core moving in a resonating pendulumatic fashion. The core converts the RF energy to infrared (IR) energy and emits IR waves through an exit aperture disposed within a hood coupled to the waveguide. A non-contact temperature measurement system measures the temperature of the core, such as using a phosphor decay temperature measurement method.
