21 Relation between Maxwellian and kappa Debye lengths 21

22 Kinetic Alfven Waves Kinetic Alfvén waves (KAWs) are the extensions of their MHD counterparts in the range of short (kinetic) cross-field wavelengths comparable to ion gyroradius or electron inertial length ion gyroradius ρ i ( ions gyromotion and pressure effects) ion gyroradius at electron temperature ρ s (shows the electron pressure effects) ion inertial length δ i (effects due to ions inertia) electron inertial length δ e (effects due to electron inertia) (KAW) (IAW) 22

23 kinetic Alfven wave: short cross-field wavelength Bo Cross-field ion currents build up ion space charges and holes Field-aligned electron currents try to compensate ion charges but fail (electron inertia and/or electron pressure effects) Parallel electric field arise 23

24 Assumptions Low frequency waves (ω << << ω ci ci ) Two potential theory Charge neutrality 24

25 Basic set of equations Linearized Poisson equation is From Maxwell equation 25

26 Perturbed distribution for ion species Where Where and 26

27 Kinetic Alfven Wave Instability Assumptions Hot and magnetized electrons Thermal and un-magnetized Lorentzian ions Cold and un-magnetized Dust Geometry Distribution function for hot and magnetized electrons 27

28 Number densities purturbations Number densities for ion, electrons and dust are found to be respectively 28

29 Current density perturbations 29

30 Placing the value of number and current density perturbations in eq. (1) and (2), we get a set of coupled equations where 30

31 Dispersion Relation Dispersion relation of KAWI is obtained by solving Several modes of propagation can be derived from this equation by considering particular limits 31

32 Dispersion Relation Whistler Waves Mix Coupled Mode This equation shows that shear Alfven wave develops a longitudinal component making KAW a mixed electrostatic and electromagnetic mode. 32

40 Conclusions Flow of Lorentzian ions have a significant effect on the wave characteristics Dust parameters have prominent effect on the growth rate of instability A high concentration of dust number density introduces upper instability which is small as compared to the lower instability Dust lower hybrid frequency (ω dlh ) arises due to the presence of hot and magnetized electrons and unmagnetized dust which provides a limit to the propagation of electromagnetic wave 40

41 Kappa has no concrete benefits for charging terms 41

42 Basic Assumptions Strongly magnetized electrons Cross field Instability Kappa distributed ions flowing perpendicular to the magnetic field (V 0 B 0 ) Cold and unmagnetized dust Geometry Distribution function 42

43 Current density of ions Number density of ions 43

44 Dispersion Relation Full dispersion equation is given by Which is the dispersion relation of electromagnetic streaming instabilities in a non-maxwellian dusty plasma Modified Two Stream Instability 44

45 In order to obtain an analytical solution w. r. t. ω, we need to approximate the Z-functions, so that the following relation is obtained 45

46 In the absence of electric current (V 0 =0 ) Which is the dispersion relation of Inertial Alfven waves with dust effects, in the limit 46

51 Conclusions Instability is found to be insensitive to Lorentzian distribution for (V 0 B 0 ) in contrast to parallel propagation (V 0 B 0 ) where it has strong influence on the growth rates By considering cold electrons we get inertial Alfven waves in low beta plasma Mobile dust introduces a new cut-off frequency which limits the motion for the propagation of electromagnetic wave. For we arrive at the dispersion curves for MTSI, whose growth rates are larger as compared to Inertial Alfven wave instability Due to particular choice of equations which involve parallel background current density, the ions electromagnetic response can not not take part which limits the existence of ions Weibel instability 51
