" ABSTRAK
Material dielektrik telah terbukti menguasai perindustrian devais elektronik seiring pesatnya perkembangan teknologi material berbasis nanostruktrur yang memiliki berbagai fungsi kerja termasuk merespon pengaruh gelombang elektromagnetik. Salah satu aplikasi material dielektrik adalah sebagai material penyerap gelombang RADAR atau Radar Absorbing Material RAM . Material dengan senyawa BaTiO3 atau Barium Stronsium Titanat BST memiliki potensial untuk menyerap gelombang elektromagnetik termasuk gelombang RADAR. Dengan demikian, material berbasis BST dapat berperan sebagai penguat filler pada sistem komposit. Pada penelitian ... "

Estimation of raindrop size distribution parameters using rain Attenuation data from a au-band communications satellite
" The rain attenuation of down-link radio wave signals from the Superbird-C satellite and surface rainfall data have been used to estimate the parameters of exponential raindrop size distribution (DSD) at Koto Tabang (100.32 E, 0.20 S), West Sumatra, Indonesia. Prior to analyzing the measured data, the ability of the method to recover the parameters of known DSDs from which the samples were taken was examined. It was found that the method can accurately retrieve the input parameter of the ... "

Absorption characteristics of the electromagnetic wave and magnetic properties of the la0.8ba0.2fexmn½(1-x)ti½(1-x)o3 (x = 0.1–0.8) perovskite system
" This paper reports on the magnetic properties and electromagnetic characterization of La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8). The La0.8Ba0.2FexMn½(1-x)Ti½(1-x)O3 (x = 0.1–0.8) materials were prepared using a mechanical alloying method. All the materials were made of analytical grade precursors of BaCO3, Fe2O3, MnCO3, TiO2, and La2O3, which were blended and mechanically milled in a planetary ball mill for 10h. The milled powders were compacted and subsequently sintered at 1000°C for 5h. All the sintered samples showed a ... "
