We present a new effective permittivity (EP) model to accurately calculate surface plasmons (SPs) using the finite-difference time-domain (FDTD) method. The computational representation of physical structures with curved interfaces causes inherent errors in FDTD calculations, especially when the numerical grid is coarse. Conventional EP models improve the errors, but they are not effective for ...

The explanation of wave behavior upon total internal reflection from a gainy medium has defied consensus for 40 years. We examine this question using both the finite-difference time-domain (FDTD) method and theoretical analyses. FDTD simulations of a localized wave impinging on a gainy half space are based directly on Maxwell's equations and make no underlying assumptions. They reveal that ampl...

With the advent of the current wireless communication revolution and the increase in its applications, the electromagnetic researchers in conjunction with the medical physicians take the initiative of studying the price of this beneficial technical revolution. It is the health hazards due to the electromagnetic radiation on the human body. The most cost efficient mean of studying these effects ...

Bu çalışmada, ağırlıkça %10, %20 ve %40 Bor Karbür (B4C) içerikli Al matris partiküllerin kompakt malzemelerin üretimi karakterizasyonu gerçekleştirilmiştir. B4C takviyeli elektriksel iletkenlik değerleri en düşük 6,97 %IACS yüksek 20,73 olarak belirlenmiştir. Deneysel çalışmalar sonucunda, mikro yapıda artan takviyesinin yapının yoğunluğunu azaltma sertliğini arttırma noktasında olumlu etkisi ...

Ground Penetrating Radar (GPR) is a shallow geophysical method for detecting and locating subsurface targets. The GPR image echo characteristics of complex underground structures can be obtained by carrying out forward modeling research. traditional finite-difference time-domain (FDTD) has low efficiency accuracy. alternating direction implicit FDTD (ADI-FDTD) algorithm surmounts the stability ...

Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder, characterised by the association of branchial, otic and renal anomalies with variable degrees of severity. We have recently identified EYA1 , a human homologue of the Drosophila eyes absent gene, as the gene underlying this syndrome. The products of both genes share a highly conserved 271 amino acid C-terminal region (eyaHR). ...

توسعه سیگنال های صوتی و تصویری با کیفیت بالا و افزایش تعداد وسایل ارتباطی در منازل اخیرا باعث افزایش تقاضا برای مخابرات بیسیم با نرخ تبادل اطلاعات بالا در فواصل نزدیک شده است. فرکانس های موج میلیمتری (30 تا 300 گیگا هرتز) یکی از بهترین گزینه ها برای این منظور می باشد. باند فرکانس موج میلیمتری بعلت پهنای باند وسیع، امکان تبادل اطلاعات تا نرخ 5 گیگا بیت بر ثانیه را فراهم می سازد. بهرحال به علت تل...

Equations applicable to finite-difference time-domain (FDTD) computation of infrasound propagation through an absorbing atmosphere are derived and examined in this paper. It is shown that over altitudes up to 160 km, and at frequencies relevant to global infrasound propagation, i.e., 0.02-5 Hz, the acoustic absorption in dB/m varies approximately as the square of the propagation frequency plus ...
