Measurements using the Transmission/Reflection line method involves placing a sample in a section of coaxial line and measuring the two ports complex scattering parameters with a vector network analyzer. For calculation of both the permittivity and permeability Nicholson-Ross-Weir method is used. Computation uncertainties problems on a complex plane are(More)
Many groups of engineers and researchers worldwide are involved in the application-oriented development of sensors. These efforts are often triggered by industrial applications and their extraordinary requirements in durability and reliability. Typical products are highly specialized sensors e.g. for temperature which are exposed to high physical and(More)
have developed a fundamentally new design of adaptive suspension systems of vehicles. Their technical characteristics and functional abilities are far better than the existing designs of suspensions. We have developed the following main suspension components of vehicles: a lockable adaptive shock absorber with an ultra-wide range of control performance,(More)
For the further development of semiconductor heterostructures and devices based on it we have to know precisely the basic parameters such as energy band discontinuities, free carriers distribution, the magnitude of the accumulated charge, etc. Physical description of systems with reduced dimensionality gives the system of Schrodinger and Poisson equations(More)
