KALI is a Virtual Cathode Oscillator which can be used for High Power Electromagnetic Pulse generation technique aka E bomb.
E Bomb are mostly created by
The Compton effect (for nuclear e-bomb)
Flux compression (for non-nuclear e-bomb)
Key technologies, which are used are explosively pumped Flux Compression Generators (FCG) , propellant driven Magneto-Hydrodynamic (MHD) generators and VIRCATOR
FCG : The flux compression is defined as compressing a large amount of flux within a low inductive region so a FCG is is a device capable of producing electrical energies of tens of Mega Joules in 1/1000 th part of a microcecond with peak power levels of the order of Tera Watts .
This FCG’s energy pulse is fed through an inductor producing a voltage which powers the vircator, which converts the energy into microwaves in the end there is an antenna that radiates the resultant high-power microwave radiation.
The lethality of the e-bomb depends chiefly on the strength of the blast that can be achieved from the explosive and proper polarization of the antenna .
Power level achieved by Vircator experiments in India ranges from 170 Kilo watts to 40 Giga watts with frequencies in the KALI .
At such energy levels KALI can fry any electronic device like for eg MOSFET can have a gate breakdown with a small amount off energy no need for a E bomb . It will be fair to say it can easily destroy a military base if dropped from a proper detonation altitude . It can be delivered through a glide bomb which by the way we are testing.
The problem is that it is very heavy in its current form i.e in 2005 and no more news is available since as it is seen as a strategic military project.

KALI is also used in DARHT ( Dual axis radiography hydrodynamic test ) facility which is used to create robust numerical hydrodynamic algorithms, databases like Equation Of State , radiative opacity, particle interaction cross-sections and material properties for extensive simulation of the hydro dynamic phenomena in critical testing of our implosion device
