Conclusions

A new parallel algorithm for an FLR fast wave code has been developed and implemented. Well converged simulations of several mode-conversion scenarios in several devices have been demonstrated. Given the scaling of resolution requirements with $\rho^*$, simulations of burning plasma experiments will require a parallel code. New physics regimes such as lower-hybrid full wave simulations are now within reach and many interesting questions such as the role of wave focusing and diffraction in LH spectral broadening may yield new insights from the full wave model. The new speeds afforded by parallel algorithms will make coupling with generalized dielectric routines and Fokker-Planck calculations of perturbed distributions possible leading to ``closed loop'' RF calculations, and realistic modeling of wave propagation in plasmas with large fusion alpha populations.
