EXPLICIT EXPRESSION FOR GROWTH-RATES IN FREE-ELECTRON LASERS WITH HELICAL AND AXIAL MAGNETIC-FIELDS
DEMOKAN, O; KABAK, Y (1992-10-01)
The dispersion relations of transverse and longitudinal modes in a free-electron laser with helical and axial magnetic fields are derived exactly for the one-dimensional case. The modes with positive and negative helicity are distinguished clearly. An analytically solvable expression for the growth rate of the modes, in resonance with the beam, is obtained. The dependence of the growth rate on system parameters is studied for broad ranges of values and comments on optimization are made.
Magnetic-Field Integral Equation [EM Programmer's Notebook]
Ofluoğlu, Atif Emre; Çiftçi, Tolga; Ergül, Özgür Salih (2015-08-01)
Although its accuracy problems have been shown many times in the literature, the magnetic-field integral equation (MFIE), either alone or in the context of the combined-field integral equation (CFIE), is still used carelessly with the conventional discretizations. In this article, we once again demonstrate the inaccuracy of the MFIE on very simple scattering problems, whose traditional solutions with the MFIE can be extremely misleading, showing the necessity of alternative discretizations.
3D forest fire propagation simulation
Koese, Kivanc; Grammalidis, Nikolaos; Yılmaz, Erdal; Cetin, Enis (2008-05-30)
The increase in the number of forest fires in the last few years dispatch governments to take precautions. Besides prevention, early intervention is also very important in fire fighting. If the firefighters know where the fire will be in some time, it would be easier for them to stop the fire. Therefore a big need for simulating the fire behavior exists. In this paper we are proposing a system which can simulate the propagation of fire in time. Also this system can visualize the propagation of fire in any 3...
