The provided data comprises input and results files pertaining to a 10×10 square array composed of randomized magnetodielectric circular cylinders. These files are instrumental for obtaining electromagnetic scattering behaviors induced by a uniform plane wave. The input file contains information on the positions, radii, relative permittivity, relative permeability, and numbers of computation modes for the elements within the square array. The results files, computed using a mode-matching technique (MMT), present the TEz- and TMz-mode echowidths for various observation angles. These calculations are conducted with the element information specified in the input file and a computation frequency of 200 GHz. Notably, the MMT is combined with an iterative method known as shooting and bouncing rays for sparse particles (SBR-SP) to accelerate the computation time for electromagnetic scattering characteristics associated with the 10×10 square array.


The input and results files have been systematically organized into separate directories based on the different rates of rainfall (Rv = 10 mm/h, 100 mm/h, and 500 mm/h).

1. Input File: rain(10x10).txt

The format of each row of the input file named "rain(10x10).txt" is as follows:

ctrX(m) ctrY(m) rad(m) real(er) imag(er) real(mr) imag(mr) nMaxModes

  • ctrX: center of x-position in meter
  • ctrY: center of y-position in meter
  • rad: radius of a cylinder in meter
  • real(er): real part of relative permittivity
  • imag(er): imaginary part of relative permittivity
  • real(mr): real part of relative permeability
  • imag(mr): imaginary part of relative permeability
  • nMaxModes: number of computation modes for each cylinder

The total number of rows in the input file is 100.

2. Results Files: Echowid(10x10,TEz).txt and Echowid(10x10,TMz).txt

The format of each row of the results files named "Echowid(10x10,TEz).txt" and "Echowid(10x10,TMz).txt" is as follows:

phi(rad) echowidth(m) real(Ds) imag(Ds)

  • phi: observation angle in radian
  • echowidth: echowidth in meter and defined in Eqn. (33) of [1] 
  • real(Ds): real part of a diffraction coefficient (Ds) defined in Eqn. (14) of [1]
  • imag(Ds): imaginary part of a diffraction coefficient (Ds) defined in Eqn. (14) of [1]

The results files named "Echowid(10x10,TEz).txt" and "Echowid(10x10,TMz).txt" were computed by the incidence of the TEz- (Ez = 0) and TMz-modes (Hz = 0), respectively. The computation frequency is 200 GHz.
