This paper presents an FMCW K-band rain radar with the property of high resolution. The radar system was designed for measurement of localized torrential rain. Using DDS and FPGA control, heterodyne modulation was used to generate the FMCW down-chirp

This paper presents the improved isolation property of the signals among transmitter and receiver antennas. The separation wall is laid at the center of the antennas to improve the isolation level between them. The introduced separation wall has serr

We previously introduced the simplified sampling biorthogonal direction implicit (SSB-ADI) method for 2-D Maxwell's equations. This paper extends it to a 3-D SSB-ADI method. Similar to the original method, the 3-D SSB-ADI method also partially uses t

This paper presents the modifled design that can reject harmonic components in the branch-line coupler. After adding open stubs at the center of branch lines of the traditional design, their new network parameters can be found in order to maintain th

This paper presents a new iterative locally one-dimensional finite-difference time-domain(LOD-FDTD) method that has a simpler formula than the original iterative LOD-FDTD formula[1]. There are fewer arithmetic operations than in the original LOD-FDTD

This letter represents a simplified sampling biorthogonal alternating-direction implicit (SSB-ADI) method based on the sampling biorthogonal time domain (SBTD) algorithm. Two sampling functions with different orders for sampling biorthogonal method a

A two-step FDTD method as a compromise of conditional stability and reduced splitting error is formulated and its numerical sta- bility is investigated. It is the perturbed form to the ADI-FDTD method by the addition of second order cross derivative

In this study, a new method is introduced to reduce the splitting error in the ADI-FDTD method using iterative method. The proposed method includes two procedures. First we solve the procedure of ADI-FDTD method and secondly a new iterative scheme is

An alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method based on the fast-adaptive-composite grid ADI (FAC-ADI) scheme is introduced to reduce the truncation error generated when ADI-FDTD is derived from the Crank-Nicolson (
