FIG. 1.

(Color online) Measured transmission spectrum for the uniform 2D square lattice PC sample without any defect. The inset shows the PC with a line defect along the direction and two horn antennas.

FIG. 2.

(Color online) (a) Equifrequency surfaces of the 2D PC which are plotted employing the plane-wave expansion method. (b) Averaged transmittance of microwaves for the frequencies from propagating along the direction as a function of position. The dotted line indicates the reference transmittance which is measured without the PC at .

FIG. 3.

(Color online) Experimentally measured transmitted (black lines) and bent (red lines) powers in the frequency range of when the line defects are made by removing (a) one row of 20 rods and (b) two rows of 20 rods along the direction.

Image of FIG. 4.
FIG. 4.

(Color online) Transmitted (black lines) and bent (red lines) powers measured for one-row line defect when (a) , (b) , and (c) in the frequency range of .

Image of FIG. 5.
FIG. 5.

(Color online) Measured powers at and calculated powers at for the transmitted and bent beams as a function of the radii of defect rods. The measured (simulated) powers are denoted by red (black) symbols.
