| 释义 |
Generally, there are two types of absorbers: resonant absorbers and broadband absorbers. The resonant absorbers are frequency-dependent because of the desired resonance of the material at a particular wavelength. Different types of resonant absorbers are the Salisbury screen, the Jaumann absorber, the Dallenbach layer, crossed grating absorbers, and circuit analog (CA) absorbers. Broadband absorbers are independent of a particular frequency and can therefore be effective across a broad spectrum.[4] References1. ^{{cite journal|doi=10.1063/1.3493736 |url=http://www.fen.bilkent.edu.tr/~bora/articles/article21_alici_JAP_2010.pdf |format=Free PDF download|title=Experimental verification of metamaterial based subwavelength microwave absorbers|year=2010|last1=Alici|first1=Kamil Boratay|last2=Bilotti|first2=Filiberto|last3=Vegni|first3=Lucio|last4=Ozbay|first4=Ekmel|journal=Journal of Applied Physics|volume=108|issue=8|pages=083113–083113–6|bibcode = 2010JAP...108h3113A |hdl=11693/11975 }} 2. ^{{cite journal|doi =10.1002/adma.201200674|pmid =22627995|title =Metamaterial Electromagnetic Wave Absorbers|year =2012|last1 =Watts|first1 =Claire M.|last2 =Liu|first2 =Xianliang|last3 =Padilla|first3 =Willie J.|journal =Advanced Materials|pages =OP98–OP120|volume=24|issue =23}} 3. ^{{cite journal|doi=10.1364/OE.19.014260 |url=http://www.opticsinfobase.org/oe/abstract.cfm?uri=oe-19-15-14260|format= Free Article download|title=Optically thin composite resonant absorber at the near-infrared band: A polarization independent and spectrally broadband configuration|year=2011|last1=Alici|first1=Kamil Boratay|last2=Turhan|first2=Adil Burak|last3=Soukoulis|first3=Costas M.|last4=Ozbay|first4=Ekmel|journal=Optics Express|volume=19|issue=15|pages=14260–7|pmid=21934790|bibcode = 2011OExpr..1914260B |hdl=11693/12111}} 4. ^{{cite book | last = Knott | first = Eugene F; John F Shaeffer and Michael T Tuley | title = Radar Cross Section | publisher = SciTech Publishing | series = SciTech Radar and Defense series | volume = | edition = Second | year = 2004 | location = Raleigh, NC | pages = 9–11, 271, 298, 313, 334, 339, 531 | language = | url = https://books.google.com/?id=0WuGjb8sqCUC&pg=PA9&dq=1.5+Absorbing+Materials#v=onepage&q=1.5%20Absorbing%20Materials&f=false | doi = | isbn =9781891121258}} Further reading
