“…A general schematic of the process is shown in Figure 4 r . g =-exp(-iy)g1_1 ---exp(iy)g_1 (5) and (2 2 r t-r g[ = exp(-iy)g1 + t exp(iy)g[1 (6) where y=-+iad For most cases of interest the magnitude of Z1 will be small.which in turn will cause r to be small in magnitude. In this case the input and output from the network are given to first order by g;f = t exp(ijy)g (11) The exponential scaling with number of nodes seen in the above equation is quite undesirable and forces stringent requirements on the switch performance and stripline losses.…”

“…Suggestions for passive waveform generators implemented in striplines range from cavity resonators for producing CWlike outputs (3)(4)(5) to nonuniform impedance striplines for producing arbitrary pulse shapes (13). In both cases the pulse from a simple generator such as that in Figure 1 is sent through what amounts to a passband filter constructed in striplines.…”

“…Real switches behave in a much less ideal fashion. A typical output from a bulk type avalanching photoconductor is shown in Figure lb Several methods for generation of more complex waveforms have been suggested and a few have been tested (2)(3)(4)(5)(6)(7). However, little has been written on the limitations of these circuits imposed by the non-ideal switch.…”

Generation of waveforms utilizing photoconductive switches and striplines has been analyzed for three circuit categories; parallel switching circuits, series switching circuits and passive waveform shaping circuits. The first two circuits utilize multiple switches to synthesize a waveform whereas the latter circuit contains a single switch in conjunction with a passive stripline circuit to generate a waveform. The properties of real switches impose practical limitations on these circuits which, in some cases, can be severe.

Abstract-A novel method allowing the ultrafast scanning of an area thanks to an Ultra Wide Band (UWB) antenna array is proposed in this paper. This method is based on the use of asynchronous optical pulses trains with different repetition rates obtained in amplified regenerative cavities. By means of optoelectronic switching, providing short powerful electrical pulses trains to an UWB antenna array, it is possible to spatially scan a large area in less than 1 ms. The paper presents the principle of the transient beam steering and its potentialities to realize an ultrafast detection system.

“…The power semiconductor switches used in ultrashort highvoltage pulse generators include a wide range of switches such as metal-oxide-semiconductor field-effect transistors (MOSFET) [14-16, 18, 19], thyristors [22] and diode opening switches [21,23]. Spark gap switches are employed in [20] while photoconductive semiconductor switches (PCSS) are used as optoelectronic switches in [24][25][26]. PCSS have two modes of operation, the linear and avalanche modes.…”

High-voltage (HV) ultrashort pulse technologies have found many applications in areas such as medicine, biology, food processing, environmental science and defense. Some applications are dependent on the pulse parameters such as duration, amplitude, shape, as well as the number of pulses applied and the frequency rate. Generators that can produce powerful electrical pulses with adjustable duration, amplitude and shape are convenient but still unusual. In this paper, we present and characterize a robust and versatile generator built on the frozen wave generator concept using photoconductive semiconductor switches. The results show that the generator can produce pulses of various shapes, peak-to-peak amplitudes up to 13.1 kV, maximum amplitudes of 6.9 kV and with durations in the nanosecond and subnanosecond range. Intense subnanosecond pulses have recently gained attention due to their potential ability to reach cells interior.Index Terms -High voltage, optoelectronic switching, versatile nanosecond and subnanosecond pulse generation, pulse shaping, biomedical applications.
