[ Description ]

M-type Barium Heksaferrite (BaFe12O19) yang disintesis dengan metode kopresipitasi digunakan sebagai filler dalam Radar Absorbent Material (RAM) dengan matriksnya adalah polyethylene therepthelate (PET). Spesimen hasil percampuran antara Barium Heksaferrite dan PET dengan variasi presentase komposisi berat yaitu 10%wt, 20%wt, dan 30%wt dari Barium Heksaferrite dikompositkan dengan menggunakan metode dallenbach layer dengan variasi ketebalan 2 mm, 4 mm, dan 6 mm. Komposit RAM kemudian diuji dengan mengunakan pengujian Vektor Network Analyzer (VNA) dengan metode Waveguide dengan frekuensi X-band (8-12 GHz) hingga didapatkan nilai reflection lossnya. Hasil pengujian VNA menunjukan nilai reflection loss terbesar adalah sampel dengan 30%wt dan ketebalan 6 mm yaitu sebesar -13,507 dB. Nilai reflection loss akan meningkat seiring dengan meningkatnya presentase berat Barium Heksaferrite dan ketebalan komposit RAM.


Alt. Description

M-type Barium Heksaferrite (BaFe12O19) were synthesized by co-precipitation method was used as filler in Radar Absorbent Material (RAM) with the matrix of therepthalate polyethylene (PET). Specimens in the result of a mixture between barium Heksaferrite and PET with variations of weight percentage composition of 10 %wt, 20%wt, and 30 wt% of barium Heksaferrite were made to a composite using dallenbach layer with thickness variation of 2 mm, 4 mm and 6 mm. The RAM Composite then tested using the test vector Network Analyzer (VNA) with a waveguide method with X-band frequencies of (8-12 GHz) to obtain the reflection loss value. VNA Test results showed the largest value of reflection loss is a sample with 30 wt% and a thickness of 6 mm that is equal to -13.507 dB. The reflection loss values will increase as the increasing of the weight percentage and the thickness of the Barium Heksaferrite RAM composite.
