Kapura I. Method of defence radiopriemnykh device from the action of electromagnetic impulses of ultra-short duration

In dissertation the scientific task of development of method of providing of functioning (to the capacity) of radio electronic apparatus is decided at influence of powerful impulsive electromagnetic radiations on the basis of the use of phase transitions in MPL and KPL of transmissions with the use of high temperature superconductors (VTSP). Superconductors protective devices, built on the basis of striplines, can be made comparatively simple technological methods, shutting out the serious affecting thin VTSP tape. Thus such protective devices assume the high degree of integration and possess comparatively small overall sizes and mass there is enough high electric durability at a maintainance. The mathematical model of description of phase transitions got further development in MPL and KPL of transmissions on the basis of high temperature superconductors, which consists in more complete formalizovannom description of law of change of superficial impedance of high temperature superconductors under act of powerful electromagnetic radiations of ultra-short duration. The offered method, consisting in presentation of MPL as a system with the up-diffused parameters, allowed to get suitable for engineerings calculations analytical expressions for the parameters of co-planar integral tls. The developed device for protecting from influence of powerful electromagnetic radiations of ultra-short pulsewidth allows to provide the reliable functioning of receiver at influence of powerful electromagnetic impulses of UKD. The method of defence of radio electronic apparatus is developed from the powerful electromagnetic impulses of ultra-short duration, which is based on the use of make-and-break properties of high temperature superconductors, arising up due to the change of superficial impedance under act of AMY.
