PDRK (http://hsxie.me/codes/pdrk/, https://github.com/hsxie/pdrk) and PDRF (http://hsxie.me/codes/pdrf/, https://github.com/hsxie/pdrf) have been renamed and updated to a new code BO (‘波’, i.e., 'wave' in Chinese), which is a state-of-art plasma wave and instability analysis tool and is being used by more and more researchers. The new version is not included in this github page yet and can be found at http://code.ennresearch.com/bo/, or http://dx.doi.org/10.17632/cvbrftzfy5.1.

PDRK is a general and powerful Kinetic Dispersion Relation solver for magnetized Plasma, which is the first kinetic dispersion relation solver that can give all the important solutions at one time without requiring initial guess for root finding.
This is an update version of pdrk-em3d code, which have fixed the bugs in the original version in [Xie2016] paper.
Also, this version is more user friendly. Several sub-files are added to separate the structures of the code.
And, most importantly, this new version we have overcome the major drawback in the original version of pdrk.
% This version (2018-10-19 version):
% 1. With loss-cone, drift bi-Maxwellian distribution;
% 2. With module to separate dispersion surfaces;
% 3. Support output polarizations, etc;
% 4. Support EM3D, ES3D and ES1D.

% 18-09-28 12:42 We find that omega_cs=-qB/m in Miyamoto2004, not the
% standard omega_cs=qB/m. This sign difference affect several terms. This
% version we have fixed the bugs of the sign of omega_cs.
% 18-10-01 09:43 based on new derivations, fixed a bug in b33 term, where a

% 18-10-13 10:37 update to with loss-cone distribution, which thus can

% 18-10-20 18:14 update to support electrostatic loss-cone.
