Modeling of Vertical Dipole Above Lossy Dielectric Half-Space: Characteristic Mode Theory
Sandip Ghosal, Arijit De, Raed M. Shubair +1
This work introduces a theoretical extension of the characteristic mode formulation for analysing the vertical electric dipole lying above a lossy dielectric half-space. As the con…
Compact Design of Dual-Band Circular Polarized Microstrip Antenna with Single Feed
Sandip Ghosal, Raed M. Shubair
A novel and compact dual band dual sense circularly polarized microstrip patch antenna with single coaxial feed has been reported in the present work. The key idea of generating du…
Near-Field Radiation Exposure Control in Slot-Loaded Microstrip Antenna: A Characteristic Mode Approach
Sandip Ghosal, Arijit De, Raed M. Shubair +1
Microstip antenna topology is commonly loaded with a narrow slot to manipulate the resonance frequency or impedance bandwidth. However, the tuning of the resonance frequency or imp…
Anomalous diffusion in an electrolyte saturated paper matrix
Sankha Shuvra Das, Sumeet Kumar, Sambuddha Ghosal +2
Diffusion of colored dye on water saturated paper substrates has been traditionally exploited with great skill by renowned water color artists. The same physics finds more recent p…
A mechanical model of bacteriophage DNA ejection
Rahul Arun, Sandip Ghosal
Single molecule experiments on bacteriophages show an exponential scaling for the dependence of mobility on the length of DNA within the capsid. It has been suggested that this cou…
Screened Coulomb Interactions With Non-uniform Surface Charge
Sandip Ghosal, John D. Sherwood
The screened Coulomb interaction between a pair of infinite parallel planes with spatially varying surface charge is considered in the limit of small electrical potentials for arbi…
