1. Many factors are involved in understanding the operation and application of frequency selective surfaces.
2. Frequency selective surface-based metamaterials block signals in one waveband and pass those at another waveband.
3. Frequency selective surfaces ( FSS ) materials can be utilized as band gap material in the surface wave domain, at microwave and radio frequency wavelengths.
4. Frequency selective surfaces ( FSS ) can exhibit subwavelength characteristics and are known variously as artificial magnetic conductors ( AMC ) or High Impedance Surfaces ( HIS ).
5. First, the series inductors will be replaced by their equivalent transmission line sections, and then the shunt capacitors will be replaced by capacitive frequency selective surfaces.
6. It's difficult to find frequency selective surfaces in a sentence. 用frequency selective surfaces造句挺難的
7. Generally speaking, metasurfaces could include some traditional concepts in the microwave spectrum such as frequency selective surface ( FSS ), impedance sheet and even Ohmic sheet.
8. Radar absorbing structures and radome, body conformal antennaea surface harde aperture, flush air data sensors and Frequency selective surface ( FSS ) radome are used to reduce radar detection.
9. He is the author of many papers on periodic surfaces and antennas, as well as two key books named " Finite Antenna Arrays and FSS " and " Frequency Selective Surfaces : Theory and Design ".
10. Frequency selective surfaces, as any type of filter, may also be classified according to their function, and these usually fall into 3 categories : low-pass, high-pass and bandpass, in addition to band-stop filters.
11. In fact, equation ( 4.2 ) is identical to the basic EFIE for a freestanding PEC FSS ( Scott [ 1989 ] or Frequency selective surface eq . ( 4.2 ) ), the only difference being the stronger singularity in 3D which accelerates convergence of the triple sums ( and the fact that the vectors are now 3-dimensional ).
12. As an example of how to use FSS equivalent circuits for quick and efficient design of a practical filter, we can sketch out the process that would be followed in designing a 5-stage Butterworth filter ( Hunter [ 2001 ], Matthaei [ 1964 ] ) using a stack of 5 frequency selective surfaces, with 4 air spacers in between the FSS sheets.
