Indonesia is necessary to develop an increase in soil productivity. The decline in soil productivity for agriculture can be caused by several factors, namely land conversion to a decrease in groundwater quantity. The actual pattern of providing irrigation... see more

Ceramics based on magnesium titanate (MgTiO3) are dielectric materials that have the potential to be used in telecommunications systems at microwave frequencies, such as filters, antennas, and signal generators. This study aims to characterize the resonan... see more

An increase in electricity generation is possible not only through the construction of power plants, but also through the creation of fundamentally new energy sources. One of the problems of modern electrical engineering is to ensure the reliability of th... see more

The paper deals with numerical solution of Maxwell equations by the method of finite differences in the time domain for bodies of revolution (BOR-FDTD) in an open domain using moving frame. The latter made possible to calculate long time propagation of a ... see more

The excitation of wake waves by the electron bunch in an isotropic plasma-dielectric waveguide is studied. It is shown that the excited field consists of two components: the field of the Langmuir wave and the field of eigenmodes of a dielectric waveguide.... see more

Traditional ceramic technology combined with a two-step sintering technique has been applied to prepare 0.96(K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 (KNLNS-BNKZ) piezoelectric ceramics. The experimental results show that the ceram... see more

The phonon dispersion curves for bulk metallic glasses (BMGs) Pd40Ni10Cu30P20 and Pd64Ni16P20 are computed for the longitudinal and transverse phonon frequencies using the simple model given by Bhatia and Singh. Different dielectric screening functions ar... see more
