The essential difference between the spectra of E- and H- polarized oscillations of complex open resonator (COR) is noted. It is evident that within the range of measurements performed for the H-polarization, only one oscillation mode is excited while in the case with the E-polarization there are excited several of such modes. In this case the self-collimation reflection from the echelette grating determines the conditions for excitation of the OR, which condition is the dispersive element forming up the OR spectrum. Some functional capabilities implied by the design of the suggested multi-mirror open resonant system are also discussed. The suggested multi-mirror open resonant system can find wide application in millimeter-wave band electronics for frequency stabilization of the electron-vacuum and solid-state devices.","PeriodicalId":235293,"journal":{"name":"2007 International Kharkov Symposium Physics and Engrg. of Millimeter and Sub-Millimeter Waves (MSMW)","volume":"182 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114105450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combination of frequency and CDMA channels separation and chaotic waveform coding for implementing CDMA standard are distinguishing features of the suggested DSRC-WDT system.

Tweeks are observed during nighttime and represent a response of the Earth-ionosphere waveguide excited by lightning strokes. Tweeks are formed by series of pulses consecutively reflected from the waveguide boundaries under different incident angles depending on a source-observer distance and effective ionosphere height along a propagation path. Using a source location technique described in our previous works we determined geometrical propagation path parameters such as source range, effective ionosphere height. We used then a time-frequency representation of the analyzed tweek waveforms to infer polarization parameters of the electromagnetic waves propagated under different incident angles as the first waveguide mode. Obtained dependencies show substantially different behavior in depend on a propagation path orientation in refer to the magnetic meridian.","PeriodicalId":235293,"journal":{"name":"2007 International Kharkov Symposium Physics and Engrg. of Millimeter and Sub-Millimeter Waves (MSMW)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114862497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
