In the study, electromagnetic weapon systems that are developed as an alternative to modern weapon systems are examined and a design for a rail type electromagnetic weapon system is intended. After a literature review on the subject, the comparison of electromagnetic and conventional weapons is made and models of electromagnetic weapons are elaborated. In the study, information of various electromagnetic weapons is provided but the focus is determined to be rail type electromagnetic weapons. Rail type electromagnetic weapons are examined in the study and the design of a low-power weapon prototype is made. For the model developed under laboratory conditions, 8 capacitors are used as a source of ignition. With the rail type electromagnetic weapon system designed, 2613.9 Joule energy is reached. The system components projected in theoretical calculations are enhanced throughout the application phase and are optimized for rail type weapon systems. For making theoretical studies and for drawing the graphs MATLAB software program is utilized. As a consequence, theoretical and empirical data is compared and commented, and some recommendations are formed.

An extremely simple first order RC high-pass filter is suggested to suppress harmful radio frequency oscillations, induced by high power electromagnetic pulses. Specifically, a broadband single stage transistor amplifier with a parasitic wiring inductance and also the parasitic junction and mounting capacitances are investigated both numerically and experimentally in the very high and ultrahigh frequency bands.

In this article we describe a novel method for the detection of explosives and other hazardous substances in the marine environment using neutron activation. Unlike the other considered methods based on this technique we propose to use guides for neutron and gamma quanta which speeds up and simplifies identification. Moreover, it may provide a determination of the density distribution of a dangerous substance. First preliminary results of Monte Carlo simulations dedicated for design of a device exploiting this method are also presented.
