UWB microstrip filter design using a time-domain technique [PDF]
, 2005 A time-domain technique is proposed for ultra-wideband (UWB) microstrip-filter design. The design technique uses the reflection coefficient (S11) specified in the frequency domain. When the frequency response of the UWB filter is given, the response will

Stable operation of a synchronously pumped colliding-pulse mode-locked ring dye laser [PDF]
, 1984 Pulses of 100-fsec duration are obtained by synchronous pumping of a colliding-pulse ring dye laser with a mode-locked Ar+-ion laser. Stable operation of the synchronously pumped colliding-pulse mode-locked laser over hours was obtained by a suitable ...

Pattern of seed longevity during storage of lentil (Lens culinaris) cultivars
The Indian Journal of Agricultural Sciences, 2023 In the present study, the viability of 36 high yielding lentil cultivars were tested at an interval of 0 (before storage), 1, 2, 3 and 4 years of storage. In all the tested varieties, themean viability was 85, 94, 94, 93 and 50% when stored for 0, 1, 2,

Instantaneous Radio Spectra of Giant Pulses from the Crab Pulsar from Decimeter to Decameter Wavelengths [PDF]
, 2006 The results of simultaneous multifrequency observations of giant radio pulses from the Crab pulsar, PSR B0531+21, at 23, 111, and 600 MHz are presented and analyzed. Giant pulses were detected at a frequency as low as 23 MHz for the first time. Of the 45

Extreme intensity pulses in a semiconductor laser with a short external cavity [PDF]
, 2013 We present a numerical study of the pulses displayed by a semiconductor laser with optical feedback in the short cavity regime, such that the external cavity round trip time is smaller than the laser relaxation oscillation period.
