  The application of plasma heating methods alternative to the direct Electron Cyclotron Resonance coupling, such as the Electron Bernstein Waves (EBW) heating, is already a reality in large-size thermonuclear reactors. These plasma waves give the unique opportunity to largely overcome the cutoff density. EBW heating in compact traps such as ECRIS devices is still a challenge, requiring advanced modelling and innovative diagnostics. At Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Sud (INFN-LNS), the off-ECR heating (driven by Bernstein waves) has produced a highly overdense plasma. Interferometric measurements say the electron density has overcome by a factor ten the cutoff density at 3.76 GHz. More advanced schemes of wave launching have been designed and implemented on the new test-bench called Flexible Plasma Trap, operating up to 7 GHz-0.5 T, in flat/simple mirror/beach magnetic configuration. The paper will give an overview about modal-conversion investigation by a theoretical and experimental point of view, including the description of the diagnostics developed to detect plasma emitted radiation in the RF, optical, soft-X and hard-X-ray domains.
