Methods of single impulse detection
Juřík, Vladimír ; Bartušek, Karel (referee) ; Fiala, Pavel (advisor)
This thesis deals with measurement method pulsed quantities of electromagnetic field. This thesis was focused on methods, which make use of optic effect. Specially Faraday effect, Pockels effect and magneto-optic Kerr effect. Next it was focused on method makes use of Rogowski coil. At the end was shortly noticed about method makes use of calorimetric sensor. For experimentally realized has been chosen Faraday Magneto-optic Effect. In optic laboratory has been realized absolute methods and different methods making use of Wollaston polarizer on pneumatic optical desk. The main advantage of this method is the capability to measure the high frequency and high current signals. Next in this thesis has been written theory about Rogowski coil. This method has been experimentally realized in laboratory.

METHODS FOR MEASUREMENT OF ULTRA-SHORT SINGLE-SHOT ELECTROMAGNETIC PULSES
Drexler, Petr ; Fiala, Pavel (advisor)
This thesis deals with the aspects of methods for pulsed high-level EM quantities measurement. Methods for current and voltage measurement in pulsed power generator and power measurement in pulse microwave generator are discussed. New approaches to single-shot measurement methods application are proposed. The theoretical analysis of suitable sensor designs is performed. The magneto-optic measurement method has been experimentally realized. On the basis of experimental results a fiber-optic current sensor has been designed and theoretically analyzed. For identification and measurement of the free-space electromagnetic pulse a combined calorimetric sensor has been designed and built.

No-radiation effects of nuclear attacks
ŠIROKÝ, Miroslav
No-radiation effects of nuclear attacks create a big group of possible impacts on society. The first task of diploma thesis is to compile basic complex of known principles, features and descriptions of behaviour of electro technical materials, mainly in the sphere of electromagnetic fields and their interaction with surroundings on various (attack induced) outer conditions. These features are verified and demonstrated through laboratory measurements taken on basic components of the latest ICT devices. The second task is to compile the whole complex of findings and observations about SW models creations on interpersonal parallel communication. Acquired results are verified on the small group of 27 people.
