The concept of higher order free space modes, gaussian-like beam modes can be applied to efficiently transport the power generated by a gyrotron for technological applications. Waveguide modes can be coupled properly to ...

The possibility to employ low power gyrotron tubes (10-30 kW, CW) at millimeter wave frequencies (30-100 GHz) has potential applications in advanced ceramic sintering, surface coating, radar, remote sensing, etc.. In ...

Usually, the gaussian beam modes are assumed to be solutions of the wave equation in the free space. Nevertheless, these modes are obtained supposing some paraxial restrictions. Therefore, we will have to check if our ...

Higher order free space modes can be considered as serious candidates for power millimeter wave transmission in advanced material processing by using medium power CW gyrotrons. These modes can be propagated in a beam ...

The use of medium power millimeter wave CW gyrotrons (10- 30 kW and 30-100 GHz) has several potential applications in advanced materials processing. Since a stochastic field distribution in the applicator is desirable ...
